New models of clean and hydrogenated amorphous silicon surfaces
Kishor Nepal, Aashish Gautam, Chinonso Ugwumadu +1
We present new atomistic models of amorphous silicon (a-Si) and hydrogenated amorphous silicon (a-Si:H) surfaces. The a-Si model included 4096 atoms and was obtained using local or…
Site-projected Thermal Conductivity: Application to defects, interfaces, and homogeneously disordered materials
A. Gautam, Y. G. Lee, C. Ugwumadu +3
With the rapid advance of high-performance computing and electronic technologies, understanding thermal conductivity in materials has become increasingly important. This study pres…
Physical origin of enhanced electrical conduction in aluminum-graphene composites
K. Nepal, C. Ugwumadu, K. N. Subedi +2
The electronic and transport properties of aluminum-graphene composite materials were investigated using ab initio plane wave density functional theory. The interfacial structure i…
