Abstract

The macroscopic nonlinear pyroelectric polarization of wurtzite Al x Ga 1- x N, In x Ga 1- x N and Al x In 1- x N ternary compounds (large spontaneous polarization and piezoelectric coupling) dramatically affects the optical and electrical properties of multilayered Al(In)GaN/GaN hetero-, nanostruct...
