Ultrafast Dynamics of Gallium Vacancy Charge States in -GaO
Arjan Singh, Okan Koksal, Nicholas Tanen +6
Point defects in crystalline materials often occur in multiple charge states. Although many experimental methods to study and explore point defects are available, techniques to exp…
Intra- and Inter-Conduction Band Optical Absorption Processes in -GaO
Arjan Singh, Okan Koksal, Nicholas Tanen +6
-GaO is an ultra-wide bandgap semiconductor and is thus expected to be optically transparent to light of sub-bandgap wavelengths well into the ultraviolet. Contrary to t…
Significantly Reduced Thermal Conductivity in Beta-(Al0.1Ga0.9)2O3/Ga2O3 Superlattices
Zhe Cheng, Nicholas Tanen, Celesta Chang +6
Beta-Ga2O3 has emerged as a promising candidate for electronic device applications because of its ultra-wide bandgap, high breakdown electric field, and large-area affordable subst…
Measurement of Ultrafast Dynamics of Photoexcited Carriers in -GaO 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 -GaO. A two-photon absorption scheme is used to photoexcite carriers with the pump pul…
Adsorption-controlled growth of La-doped BaSnO3 by molecular-beam epitaxy
Hanjong Paik, Zhen Chen, Edward Lochocki +14
Epitaxial La doped BaSnO3 films were grown in an adsorption controlled regime by molecular beam epitaxy, where the excess volatile SnOx desorbs from the film surface. A film grown…
