Stark Effect Suppression in (In,Ga)N Nanoheterostructures
Purdue MSE, CGT, and ECE researchers have demonstrated geometries that suppress the pyroelectric and piezoelectric-induced Stark Effect from nanorods for (In,Ga)N-based light-emitting diodes. By controlling the aspect ratio of the deposited layers, their deleterious effects on optoelectronic performance can be mitigated.
