Optical spin injection in graphane and fluorographene
Angélica Marina López-MartÃnez, César Castillo-Quevedo, Cesar Camas-Flores +2
We theoretically investigate the optical spin-injection response in different stoichiometric configurations of graphane and fluorographene using density functional theory. Our goal…
Unveiling AlSb as a Promising Zincblende Semiconductor for Visible-Light Shift-Current Generation
César Castillo-Quevedo, Edgar Paredes-Sotelo, Peter L. RodrÃguez-Kessler +2
We use density functional theory to investigate the shift-current response in zincblende III--V (AlP, AlAs, AlSb, GaP, GaAs, InP, InAs, and InSb) and II--VI (ZnS, ZnSe, ZnTe, CdS,…
Insulating moiré homobilayers lack a threefold symmetric second harmonic generation
Luis Enrique Rosas-Hernandez, Jose Luis Cabellos, Angiolo Huamán +2
Atoms within moiré bilayers relax in-plane to minimize elastic energy [e.g., Cazeaux et al., J. Elast. 154, 443 (2023)]; such relaxation brings their space group symmetries down t…
