Impact of second-order piezoelectricity on electronic and optical properties of $c$-plane In${}_x$Ga${}_{1-x}$N quantum dots: Consequences for long wavelength emitters

Saroj Kanta Patra, Stefan Schulz

In this work we present a detailed analysis of the second-order piezoelectric effect in $c$-plane In${}_x$Ga${}_{1-x}$N/GaN quantum dots and its consequences for electronic and optic…
