TL;DR: Comparison between polariton lasing and photon lasing in a ZnO-based hybrid microcavity under optical pumping is done in terms of the linewidth broadening, blue-shift of the emission peak, and polarization.

TL;DR: In this article, the authors reported the growth and characterization of bulk ZnO-based hybrid microcavity, which consists of 30 pair epitaxially grown AlN/AlGaN distributed Bragg reflector (DBR) on the bottom side of the 3/2λ thick ZNO cavity and 9 pair SiO2/HfO2 DBR as the top mirror.

TL;DR: In this paper, the effect of Auger recombination loss on efficiency droop by taking dif- ferent Auger coefficients into account is discussed. And the simulation results show that the wavelength-dependent efficiency droops is caused by sev- eral different effects including non-uniform carrier distrib- ution, electron overflow, built-in electrostatic field induced by spontaneous and piezoelectric polarization, and Auger loss.

TL;DR: A clear polariton relaxation bottleneck is observed at low temperature and large negative cavity detuning conditions and is suppressed with increasing temperature and decreasing detuning, due to more efficient phonon-assisted relaxation and a longer radiative lifetime of the polaritons.

TL;DR: In this paper, the basal plane stacking faults (BSFs) related optical properties in a-plane AlGaN alloys with different Al composition ranging from 0 to 0.28 were studied.
