Abstract

Silicon, a ubiquitous element in modern electronics, underpins the operation of countless devices due to its unique semiconducting properties. However, as device dimensions shrink to the nanoscale, silicon-based devices face limitations such as increased power consumption and decreased performance. Coating silicon with graphene is aimed to improve the device performance and extend the limits of silicon’s performance. Conducting experimental work involving graphene for thin coatings is a resource-intensive process. Hence, molecular dynamics (MD) simulation is necessary to illuminate the evaporation and coating mechanisms at the atomic scale, serving as a valuable tool for experimental design. These molecular dynamics simulations have elucidated the intricate relationship between temperature and deposition time in governing the quantity and spatial distribution of carbon atoms on a silicon substrate. Within a 300 ps deposition interval, a non-linear correlation between temperature and carbon deposition is observed, indicating that the allotted time is insufficient for complete atomic diffusion and homogeneous distribution. At elevated temperatures, carbon atoms accumulate, impeding the diffusion of subsequent atoms. Conversely, a 600 ps deposition period reveals a direct proportionality between temperature and carbon deposition, attributed to the enhanced mobility of carbon atoms, facilitating their dispersion and creation of vacancies within the substrate.

Abstract

Purwodadi Village is located in the southern part of Malang Regency with a karst area which presents a beautiful panorama of rock outcrops and forms a collection of geological sites, so this area has the potential to be developed as a geotourism. Optimizing the use of geological sites and digital technology in the tourism sector will bring extraordinary benefits. This service activity aims to socialize the empowerment of geological sites to support Purwodadi Tourism Village as a geotourism centre. This activity is in collaboration with the Purwodadi Village-Owned Enterprise "Dadi Mulyo" and the Purwodadi Village Government, who also participate in the activity. The socialization is carried out to provide an overview and demonstration of the empowerment of geological sites as well as efforts that can be made to introduce geological sites to the wider community, such as digitization through the website. While the geological survey aims to map the variety of geological sites owned by Purwodadi Village, which have the potential to attract visitors. The final target of this activity is to increase the number of tourist visitors in the hope of increasing income generating BUMDes and the local government.
