Collective Electrostatics and Band Alignment in Janus MoSTe nanotubes
Adithya Sadanandan, Tyson Karl, Rahil Shaik +1
In this work, we investigate the collective electrostatic effects of one-dimensional (1D) Janus MoSTe nanotubes and their impacts on the band alignment of nanotube heterostructures…
Analytical Theory of Near-Field Electrostatic Effects in Two-Dimensional Materials and van der Waals Heterojunctions
Qunfei Zhou, Michele Kotiuga, Pierre Darancet
We derive and validate a quantitative analytical model of the near-field electrostatic effects in the vicinity (>=3Å) of two-dimensional (2D) materials. In solving the Poisson equa…
A Review of Sc-containing "Scandate" Thermionic Cathodes
Mujan N. Seif, Qunfei Zhou, Xiaotao Liu +2
Although thermionic emission has been studied for more than 100 years, recent interest in novel electron devices for military and civilian use has led to a surge in demand for cath…
Engineering the Electronic Structure of Two-Dimensional Materials with Near-Field Electrostatic Effects of Self-Assembled Organic Layers
Qunfei Zhou, Bukuru Anaclet, Trevor Steiner +2
We compute the electronic structure of two-dimensional (2D) materials decorated with self-assembled organic monolayers using density functional theory. We find that 2D materials ar…
Range-Separated Hybrid Functionals for Mixed-Dimensional Heterojunctions: Application to Phthalocyanines/MoS2
Qunfei Zhou, Zhen-Fei Liu, Tobin J. Marks +1
We analyze the electronic structure and level alignment of transition-metal phthalocyanine (MPc) molecules adsorbed on two-dimensional MoS employing density functional theory (…
Non-Abelian Stokes theorem and quantized Berry flux
Alexander C. Tyner, Shouvik Sur, Qunfei Zhou +4
Band topology of anomalous quantum Hall insulators can be precisely addressed by computing Chern numbers of constituent non-degenerate bands that describe quantized, Abelian Berry…
