Symmetry breaking structural relaxation and optical transitions of native defects and carbon impurities in LiGaO
Klichchupong Dabsamut, Adisak Boonchun, Walter R. L. Lambrecht
LiGaO in a spinel type structure has recently been claimed to be an unintentional p-type ultra-wide-band-gap oxide semiconductor. While previous computational work did not…
Band structure and excitonic properties of WSe in the isolated monolayer limit in an all-electron approach
Niloufar Dadkhah, Walter R. L. Lambrecht
A study is presented of the electronic band structure and optical absorption spectrum of monolayer WSe using an all-electron quasiparticle self-consistent approach, QS$G\h…
Comparison of interband related optical transitions and excitons in ZnGeN and GaN
Ozan Dernek, Walter R. L. Lambrecht
The optical dielectric function of ZnGeN is calculated from the interband transitions using the energy bands calculated in the quasiparticle self-consistent (QS) metho…
Computational study of defect complexes in -LiGaO and their relation to the donor-acceptor-pair recombination
Klichchupong Dabsamut, Adisak Boonchun, Walter R. L. Lambrecht
Hybrid functional calculations are presented for defects in LiGaO with the fraction of non-local exchange adjusted to reproduce the recently reported exciton gap of 6.0 eV. We…
Improved quasiparticle self-consistent electronic band structure and excitons in -LiGaO
Niloufar Dadkhah, Walter R. L. Lambrecht, Dimitar Pashov +1
The band structure of -LiGaO is calculated using the quasiparticle self-consistent QS method where the screened Coulomb interaction is evaluated including…
Robustness of electronic screening effects in electron spectroscopies: example of VO
Vitaly Gorelov, Lucia Reining, Walter R. L. Lambrecht +1
In bulk and low-dimensional extended systems, the screening of excitations by the electron cloud is a key feature governing spectroscopic properties. Widely used computational appr…
