Abstract

Technological processes for modification of materials, deposition, and prevented fumes in the pyrolysis processes are used gases materials in the medium with vacuum pressure or atmospheric air pressure. Therefore, it is essential to understand heat flow transport for designing an efficient reactor or find the substrate's excellent position in the reactor or furnace for growing materials. We evaluated the energy transfer phenomena in the form of temperature distribution and heat flow for various heating sources for the gases and solid materials by Gauss-Seidel equation. The thermal conductivity coefficient (k), number of heating sources, and position of heating sources show an essential parameter for transmitting the distribution of the heat. For high k value shows efficiently for heat transfer at low temperature due to the atom's position close each other. The heat also affects to the phonon and lattice vibration like a wave which  successfully shows these phenomena in this study.

Abstract

This review focus on the effect of doping rare earth metals, transition metals, noble metals, poor metals, and non-metals on ZnO nanoparticles. ZnO is a semiconductor material with an average wide energy band gap of 3.2 eV. The doping is used to improve the properties of ZnO which strongly depend on their application. The concentration of doping, the type of doping and the process using sol-gel, hydrothermal and precipitation methods are affected in modifying the ZnO lattice parameters. The transition metal widely used for photocatalysts and sensors. The doped application of ZnO nanoparticles as a semiconductor material has proven advantageous in enabling various photocatalytic, glucose biosensors, VOC detection sensors, antibacterial, biomedical, and optoelectronic spintronic, LED, NLO, and silicon solar cells. This review provided information for scientist in choosing the synthesizing methods of ZnO with desired properties and application in future.
