Vacancy Relaxation in Cuprous Oxide (CuO)
Laszlo Frazer, Kelvin B. Chang, Richard D. Schaller +2
Phonons are produced when an excited vacancy in cuprous oxide (CuO) relaxes. Time resolved luminescence was used to find the excited copper vacancy (acceptor) and oxygen vacanc…
Evaluation of defects in cuprous oxide through exciton luminescence imaging
Laszlo Frazer, Erik J. Lenferink, Kelvin B. Chang +3
The various decay mechanisms of excitons in cuprous oxide (Cu2O) are highly sensitive to defects which can relax selection rules. Here we report cryogenic hyperspectral imaging of…
Photoionization cross section of 1s orthoexcitons in cuprous oxide
Laszlo Frazer, Kelvin B. Chang, Kenneth R. Poeppelmeier +1
We report measurements of the attenuation of a beam of orthoexciton-polaritons by a photoionizing optical probe. Excitons were prepared in a narrow resonance by two photon absorpti…
Third Harmonic Generation in Cuprous Oxide: Efficiency Determination
Laszlo Frazer, Richard D. Schaller, Kelvin Chang +2
The efficiency of third harmonic generation in cuprous oxide was measured. Intensities followed a non-cubic power law which indicates nonperturbative behavior. Polarization anisotr…
