Measurement of Ultrafast Dynamics of Photoexcited Carriers in $β$ -Ga $_{2}$ O $_{3}$ by Two-Color Optical Pump-Probe Spectroscopy

Okan Koksal, Nicholas Tanen, Debdeep Jena +2

We report results from ultrafast two-color optical pump-probe spectroscopy on bulk $β$ -Ga $_{2}$ O $_{3}$ . A two-photon absorption scheme is used to photoexcite carriers with the pump pul…

Interaction-driven spin-orbit effects and Chern insulating phases in corundum-based $4 d$ and $5 d$ oxide honeycomb lattices

Okan Köksal, Rossitza Pentcheva

Using density functional theory calculations with a Hubbard $U$ , we explore topologically nontrivial phases in $X_{2}$ O $_{3}$ honeycomb layers with $X =$ $4 d$ and $5 d$ cation inserted i…
