DFT+DMFT calculations of the complex band and tunneling behavior for the transition metal monoxides MnO, FeO, CoO and NiO
Long Zhang, Peter Staar, Anton Kozhevnikov +4
We report complex band structure (CBS) calculations for the four late transition metal monoxides, MnO, FeO, CoO and NiO, in their paramagnetic phase. The CBS is obtained from densi…
All-electron self-consistent GW in the Matsubara-time domain: implementation and benchmarks of semiconductors and insulators
Iek-Heng Chu, Jonathan P. Trinastic, Yun-Peng Wang +4
The GW approximation is a well-known method to improve electronic structure predictions calculated within density functional theory. In this work, we have implemented a computation…
Preventing rapid energy loss from electron-hole pairs to phonons in graphene quantum dots
Jonathan Trinastic, Iek-Heng Chu, Hai-Ping Cheng
In semiconductors, photoexcited electrons and holes (carriers) initially occupy high-energy states, but quickly lose energy to phonons and relax to the band edge within a picosecon…
First-principles study of multi-control graphene doping using light-switching molecules
Jonathan Trinastic, Hai-Ping Cheng
The high carrier mobility in graphene promises its utility in electronics applications. Azobenzene is a widely studied organic molecule for switchable optoelectronic devices that c…
Using Light-Switching Molecules to Modulate Charge Mobility in a Quantum Dot Array
Iek-Heng Chu, Jonathan Trinastic, Lin-Wang Wang +1
We have studied the electron hopping in a two-CdSe quantum dot system linked by an azobenzene-derived light-switching molecule. This system can be considered as a prototype of a QD…
First-principles study of Co concentration and interfacial resonance states in FeCo magnetic tunnel junctions
Jonathan Trinastic, Yan Wang, Hai-Ping Cheng
The optimal Co concentration in FeCo/MgO magnetic tunnel junctions (MTJs) that maximizes tunneling magnetoresistance (TMR) is still under investigation. We perform a…
