Mapasha, Refilwe Edwin; Ukpong, Aniekan M.; Chetty, Nithaya (American Physical Society, 2012-05)We present a comparative density functional study of the adsorption of hydrogen on bilayer graphene. Six different exchange-correlation functionals are employed to explore the possible configurations of hydrogen ad- sorption ...

Ngwenya, T. Bongani; Ukpong, Aniekan M.; Chetty, Nithaya (American Physical Society, 2011-12)First principles calculations have been performed to investigate the ground state properties of freestanding monolayer hexagonal boronitrene (h-BN). We have considered monolayers that contain native point defects and ...

Ukpong, Aniekan M.; Chetty, Nithaya (IOP Publishing, 2012-05)The van der Waals interaction-corrected density functional theory is used in this study to investigate the formation, energetic stability, and inter-layer cohesion in bilayer hexagonal boronitrene. The effect of inter-layer ...

Ukpong, Aniekan M.; Chetty, Nithaya (IOP Publishing, 2012-06)We present the results of first principles molecular-dynamics simulations of nitrogen vacancy complexes in monolayer hexagonal boron nitride. The threshold for local structure reconstruction is found to be sensitive to the ...

Ukpong, Aniekan M. (Elsevier, 2015-03)This paper presents a comparative first principles study of van derWaals heterobilayers derived from the coupling of graphene to silicon carbide and hexagonal boron nitride monolayer. Using the local, semilocal, and van ...

Ukpong, Aniekan M.; Chetty, Nithaya (American Physical Society, 2012-11)We perform first principles molecular dynamics simulations to investigate the magnetoelectronic response of substitutionally-doped boronitrene to thermal excitation. We show that the local geometry, size and edge-termination ...
