Robust electric-field tunable opto-electrical behavior in Pt-NiO-Pt planar structures.

TL;DR: The electroformed Pt-NiO-Pt planar structures exhibit a nonlinear rectification behavior and a remarkable photoresponse at low voltage biases and show a dramatic change of sign of rectification under light illumination at higher voltage biases.

Origin of efficiency droop in GaN-based light-emitting diodes

TL;DR: In this paper, the efficiency droop in GaInN∕GaN multiple-quantum well (MQW) light-emitting diodes was investigated and it was shown that the droop is not related to MQW efficiency but rather to the recombination of carriers outside the MqW region.
