Abstract

Semiconductors are materials with interesting electrical properties. Copper tin oxide (CuSnO3) is an oxide semiconductor material with a band gap value of 2.0-2.5 eV. The method used is sol-gel method with the addition of monoethanolamine (MEA). Copper (II) nitrate trihydrate and tin (II) chloride dihydrate as precursors and methanol as solvent. The purpose of this research is to see the effect of MEA addition on the electrical properties of CuSnO3. Characterization results using UV-DRS showed the band gap of CuSnO3 obtained with the addition of 1.5 mL of MEA was 1.71 eV and without the addition of MEA was 2.36 eV. The addition of MEA can reduce the band gap value. Electrical conductivity will be better with the smaller band gap value.

Abstract

Research on the degradation of methyl orange dye using the photolysis method using a copper tin oxide (CuSnO3) catalyst has been carried out. The aim of this research is to see how catalyst activity influences variations in methyl orange degradation time, whether the addition of MEA (Monoethanolamine) is more effective for photocatalyst applications. In this research, a concentration of 10 ppm of methyl orange was used, 40 mL of which was degraded with a CuSnO3 catalyst of 0.05 grams. This degradation process involves treatments including CuSnO3 catalyst without MEA; 1 mL, 1.5 mL, and 2 mL MEA. The characterization used in this research is UV – VIS. The analysis results showed that the percentage of degradation without MEA at a time variation of 240 minutes was 64.43%, while at 1 mL it was 19.77%, 1.5 mL 16.92%, and 2 mL 20.91%.

Abstract

The main semiconductor materials used are the elements Ge (germanium) and Si (silicon). The element Ge is found in nature in small quantities and silicon is the most abundant element in the earth's crust but its conductivity is low. The semiconductor material that has recently been frequently researched is Copper Tin Oxide (CuSnO3). CuSnO3 has high electrical conductivity and is quite abundant on the earth's surface. The synthesized CuSnO3 semiconductor is applied as a thin layer because of several advantages such as large output voltage, small electrode mass, and also a fairly long service life. This research aims to determine the optical and electrical properties of CuSnO3 thin films synthesized using the sol-gel method with dip coating techniques. CuCl2·2H2O, SnCl2·2H2O, methanol, and monoethanolamine (MEA) are the precursors used. The synthesized CuSnO3 thin layer was characterized using a UV-DRS instrument to determine the band gap value and tested using the four point probe method to determine its electrical conductivity. The band gap values with calcination temperatures of 500°C, 550°C, and 600°C are 2.55 eV, 2.83 eV, and 2.95 eV, respectively, with electrical conductivity of 348.46 102 S/cm, 155.48 102 S/cm, and 107.63 102 S/cm. From these data it can be concluded that the band gap value of the CuSnO3 thin layer will increase when the calcination temperature used is higher, and the conductivity decreases as the band gap value of the CuSnO3 thin film increases.

Abstract

Copper(II) oxide (CuO) has been recognized as a promising semiconductor material for various applications, such as photocatalysis, sensors, and renewable energy devices. However, its efficiency is often limited by a suboptimal bandgap value. This study aims to analyze the effect of cerium doping on the properties of CuO nanoparticles synthesized through the sol-gel process. The sol-gel method ensures a homogeneous doping distribution and produces nanoparticles with a stable structure. The bandgap energy of CuO nanoparticles was determined through characterization using UV-DRS. Cerium was introduced as a dopant in CuO at a concentration of 0.4 mmol, resulting in a bandgap value of 1.26 eV, whereas undoped CuO exhibited a bandgap of 1.35 eV. The analysis indicates that the Ce doping concentration significantly affects the bandgap of CuO nanoparticles, with a reduction observed at 0.4 mmol compared to undoped CuO. This decrease is attributed to symmetry disruption caused by doping, including oxygen vacancies, structural defects, and the presence of impurities that create additional energy levels within the bandgap. Furthermore, uniform microstrain and a smaller particle size contribute to structural disturbances that also influence the bandgap.

Abstract

Semiconductors are materials used to conduct electricity for a certain period of time. SnO2 is an n-type semiconductor that has a wide band gap and is most widely used in technology such as solar cells, batteries, and catalysts. This study aims to analyze the effect of vanadium doping on the properties of SnO2 nanoparticles using the sol-gel method. The sol-gel method can produce a stable vanadium-doped SnO2 surface and has a high surface area. Determination of the band gap energy value in SnO2 was carried out by characterization using UV-DRS. The results of SnO2 doped with vanadium obtained the optimum bandgap value at the addition of vanadium with a concentration of 0.25 mmol, which is 2.25 eV and SnO2 without the addition of vanadium doping has a bandgap value of 3.41 eV. This shows that the addition of vanadium doping can affect the bandgap value of SnO2 nanoparticles. This decrease in the bandgap value is caused by the interaction between the electron band and the delocalization of electrons in the transition ions causing metal ion substitution, which results in a decrease in the bandgap value.

Abstract

This study focuses on the synthesis of CuSnO3 thin films using the sol-gel dip coating method, with a particular emphasis on the effects of diethanolamine (DEA) addition and calcination temperature on the bandgap energy. The successful addition of DEA significantly influenced the reduction of the bandgap energy of CuSnO3 thin films, decreasing from 3.21 eV (without DEA) to 2.11 eV (optimal DEA addition, 1.5 mL), as characterized by UV-DRS. Furthermore, different calcination temperatures yielded varying bandgap energies, with the lowest bandgap energy observed in samples calcined at 550°C. This research provides valuable insights into the manipulation of CuSnO3 thin film properties for potential applications in optoelectronic devices and other emerging technologies.

Abstract

Solar cell technology is a technology that can create electrical energy using semiconductor devices that have p-n connections. Copper tin oxide CuSnO3 (CSO) is an amorphous oxide semiconductor with a band gap of 2.0–2.5 eV. The method used is sol gel with the addition of one of the commonly used additives, namely Monoethanolamine (MEA). This research aims to determine the effect of monoethanolamine additives on the crystal structure of Copper Tin Oxide using the Sol Gel method. This research is quantitative research by collecting data from previous research and then conducting research using specified methods and objects. The results of research using XRD showed particle sizes ranging from 40.10 – 50.02 nm and the results obtained without additives were 21.06 nm. This is because the addition of additives greatly influences the crystal size and crystal Structure.

Abstract

This study investigated a thin layer of CuSnO3 synthesized through sol-gel dip-coating method with variations in the addition of monoethanolamine. The results revealed that the addition of monoethanolamine by 1 ml reduced the band gap value to 2.2 eV, while the thin layer without the addition of monoethanolamine had a band gap value of 3.1 eV. In addition, the variation in the number of coatings also affects the band gap, where a maximum value of 2.1 eV is obtained with 2 times of coating. These results highlight the importance of monoethanolamine addition and coating amount in regulating the optical properties of CuSnO3 thin layers. The large amount of coating causes an increase in the band gap value and the addition of Monoethanolamine affects the CuSnO3 band gap value.

Abstract

A thin layer is a layer made from organic or non-organic materials which are semiconductors, conductors and insulators. This research aims to determine the effect of precursor concentration on the electrical properties of thin films. Variations in precursor concentration used were 0.025 M, 0.05 M, and 0.075 M. CuSnO3 thin films were characterized by UV-DRS, XRD, FPP, and SEM. The method used in this research is sol-gel. The sol-gel process is used because of its ability to control the surface properties of oxide composites. The results of the band-gap test the variation in precursor concentration obtained by the band-gap value becomes smaller with increasing concentration. The lowest band-gap value in variations in adding an MEA volume of 2 ml, the optimum band-gap value is 2.1706 eV. The results of the FPP test on a thin layer of CuSnO3 precursor concentration of 0.05 M with an optimum MEA of 2 ml obtained a resistivity value of 0.0005671 Ωm with a conductivity value of 173.5809 Ω^(-1) m^(-1).
