First-principles-derived effective mass approximation for the improved description of quantum nanostructures
Hyeonwoo Yeo, Jun Seong Lee, Muhammad Ejaz Khan +3
The effective mass approximation (EMA) could be an efficient method for the computational study of semiconductor nanostructures with sizes too large to be handled by first-principl…
Controlling transport properties of graphene nanoribbons by codoping-induced edge distortions
Hyo Seok Kim, Seong Sik Kim, Han Seul Kim +1
One notable manifestation of the peculiar edge-localized states in zigzag graphene nanoribbons (zGNRs) is the p-type (n-type) characteristics of nitrogen (boron) edge-doped GNRs, a…
Carbon nanobuds based on carbon nanotube caps: A first-principles study
Ji Il Choi, Hyo Seok Kim, Han Seul Kim +3
Based on density functional theory calculations, we here show that the formation of a fullerene C carbon "nanobud" (CNB) on carbon nanotube (CNT) caps is energetically more…
Atomistic Mechanisms of Codoping-Induced p- to n-Type Conversion in Nitrogen-Doped Graphene
Hyo Seok Kim, Han Seul Kim, Seong Sik Kim +1
It was recently shown that nitrogen-doped graphene (NG) can exhibit both p- and n-type characters depending on the C-N bonding nature, which represents a significant bottleneck for…
Conductance recovery and spin polarization in boron and nitrogen codoped graphene nanoribbons
Seong Sik Kim, Han Seul Kim, Hyo Seok Kim +1
We present an ab initio study of the structural, electronic, and quantum transport properties of B-N-complex edge-doped graphene nanoribbons (GNRs). We find that the B-N edge codop…
