Nonlocal Electrostatic Origin of Schottky-Barrier Variability in 2D Contacts
Hangbo Zhou, Yong-Wei Zhang
Electrical contacts often limit the performance of atomically thin semiconductor devices. The Schottky barrier height (SBH) is conventionally treated as a local interface property,…
The effects of point defect type, location, and density on the Schottky barrier height of Au/MoS2 hetero-junction: A first-principles study
Viacheslav Sorkin, Hangbo Zhou, Zhi Gen Yu +2
Using DFT calculations, we investigate the effects of the type, location, and density of point defects in monolayer MoS2 on electronic structures and Schottky barrier heights (SBH)…
Effects of high order interatomic potential on elastic phonon scatterings
Hangbo Zhou, Gang Zhang, Yong-Wei Zhang
Interatomic potentials beyond quadratic order provide scattering sources for phonon transport in lattice. By using a weakly-interacting interface model, we investigated the relatio…
Anharmonic quantum thermal transport across a van der Waals interface
Hangbo Zhou, Gang Zhang, Jian-Sheng Wang +1
We investigate the anharmonic phonon scattering across a weakly interacting interface by developing a quantum mechanics-based theory. We find that the contribution from anharmonic…
Three-terminal interface as a thermoelectric generator beyond Seebeck effect
Hangbo Zhou, Gang Zhang, Jian-Sheng Wang +1
We investigate thermoelectric transport through interfaces with inelastic scatterings by developing a quantum theory, which has been extensively validated by existing theories. We…
Superior lattice thermal conductance of single layer borophene
Hangbo Zhou, Yongqing Cai, Gang Zhang +1
By way of the nonequilibrium Green's function simulations and first principles calculations, we report that borophene, a single layer of boron atoms that was fabricated recently, p…
Phonon transport in a one-dimensional harmonic chain with long-range interaction and mass disorder
Hangbo Zhou, Gang Zhang, Jian-Sheng Wang +1
Atomic mass and interatomic interaction are the two key quantities that significantly affect the heat conduction carried by phonons. Here, we study the effects of long-range (LR) i…
Quantum thermal transport in stanene
Hangbo Zhou, Yongqing Cai, Gang Zhang +1
By way of the non-equilibrium Green's function simulations and analytical expressions, the quantum thermal conductance of stanene is studied. We find that, due to the existence of…
Boosting thermoelectric efficiency using time-dependent control
Hangbo Zhou, Juzar Thingna, Peter Hänggi +2
Thermoelectric efficiency is defined as the ratio of power delivered to the load of a device to the rate of heat flow from the source. Till date, it has been studied in presence of…
Effects of electron-phonon interaction on thermal and electrical transport through molecular nano-conductors
Jing-Tao Lü, Hangbo Zhou, Jin-Wu Jiang +1
The topic of this review is the effects of electron-phonon interaction (EPI) on the transport properties of molecular nano-conductors. A nano-conductor connects to two electron lea…
Thermoelectric transport through a quantum nanoelectromechanical system and its backaction
Hangbo Zhou, Juzar Thingna, Jian-Sheng Wang +1
We present a comprehensive study of thermoelectric transport properties of a quantum nanoelectromechanical system (NEMS) described by a single-electron-transistor (SET) coupled to…
Improved Dyson series expansion for steady-state quantum transport beyond the weak coupling limit - divergences and resolution
Juzar Thingna, Hangbo Zhou, Jian-Sheng Wang
We present a general theory to calculate the steady-state heat and electronic currents for nonlinear systems using a perturbative expansion in the system-bath coupling. We explicit…
