Electronic transport in copper-graphene composites
K. N. Subedi, K. Nepal, C. Ugwumadu +2
We investigate the electronic transport properties of copper-graphene composites using a density-functional framework. Conduction in composites by varying the interface distance of…
Formation of amorphous carbon multi-walled nanotubes from random initial configurations
C. Ugwumadu, R. Thapa, Y. Al-Majali +2
Amorphous carbon nanotubes (a-CNT) with up to four walls and sizes ranging from 200 to 3200 atoms have been simulated, starting from initial random configurations and using the Gau…
Atomistic Nature of Amorphous Graphite
C. Ugwumadu, K. Nepal, R. Thapa +1
This paper focuses on the structural, electronic, and vibrational features of amorphous graphite [R. Thapa , Phys. Rev. Lett. 128, 236402 (2022)]. The structure o…
Ab initio simulation of amorphous graphite
Rajendra Thapa, Chinonso Ugwumadu, Kishor Nepal +2
A disorder-order transition from amorphous carbon (aC) to layered amorphous graphene (LAG) has been predicted using ab-initio methods. Amorphous carbon at densities close to the gr…
