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…
The Structure and Dispersion of Exciton-Trion-Polaritons in Two-Dimensional Materials: Experiments and Theory
Okan Koksal, Minwoo Jung, Christina Manolatou +3
The nature of trions and their interaction with light has remained a puzzle. The composition and dispersion of polaritons involving trions provide insights into this puzzle. Trions…
Exciton-Trion-Polaritons in Two-Dimensional Materials
Farhan Rana, Okan Koksal, Minwoo Jung +3
We present a many-body theory for exciton-trion-polaritons in doped two-dimensional materials. Exciton-trion-polaritons are robust coherent hybrid excitations involving excitons, t…
Many-body theory of radiative lifetimes of exciton-trion superposition states in doped two-dimensional materials
Farhan Rana, Okan Koksal, Minwoo Jung +2
Optical absorption and emission spectra of doped two-dimensional (2D) materials exhibit sharp peaks that are often identified with pure excitons and pure trions (or charged exciton…
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…
A Many-Body Theory of the Optical Conductivity of Excitons and Trions in Two-Dimensional Materials
Farhan Rana, Okan Koksal, Christina Manolatou
The optical spectra of two dimensional (2D) materials exhibit sharp absorption peaks that are commonly identified with exciton and trions (or charged excitons). In this paper, we s…
