Tracking the electronic oscillation in molecule with tunneling microscopy
Rulin Wang, Fuzhen Bi, Wencai Lu +2
Visualizing and controlling electron dynamics over femtosecond timescale play a key role in the design of next-generation electronic devices. Using simulations, we demonstrate the…
Complex absorbing potential based Lorentzian fitting scheme and time dependent quantum transport
Hang Xie, Yanho Kwok, Feng Jiang +2
Based on the complex absorbing potential (CAP) method, a Lorentzian expansion scheme is developed to express the self-energy. The CAP-based Lorentzian expansion of self-energy is e…
A gauge-invariant and current-continuous microscopic ac quantum transport theory
JianQiao Zhang, ZhenYu Yin, Xiao Zheng +2
There had been consensus on what the accurate ac quantum transport theory was until some recent works challenged the conventional wisdom. Basing on the non-equilibrium Green's func…
Equivalent electric circuit of a carbon nanotube based molecular conductor
ChiYung Yam, Yan Mo, Fan Wang +6
We apply our first-principles method to simulate the transient electrical response through carbon nanotube based conductors under time-dependent bias voltages, and report the dynam…
The roles of apex dipoles and field penetration in the physics of charged, field emitting, single-walled carbon nanotubes
Jie Peng, Zhibing Li, Chunshan He +8
A 1 m long, field emitting, (5,5) single-walled, carbon nanotube (SWCNT) closed with a fullerene cap, and a similar open nanotube with hydrogen-atom termination, have been simul…
Atomic decoration for improving the efficiency of field electron emission of carbon nanotubes
Guihua Chen, Zhibing Li, Jie Peng +9
The field electron emission from the single-walled carbon nanotubes with their open ends terminated by -BH, -NH, and -O has been simulated. The apex-vacuum barrier and the emission…
