Vacuum ultraviolet dielectric function of cubic InGaN for the entire composition range

The cubic zincblende polymorph of InGaN is a very promising candidate for optical applications. Its absence of spontaneous polarization fields in the (001) orientation and lower fundamental band gap compared to its wurtzite counterpart makes it especially interesting for efficien...

Analyzing the interface properties of cubic GaN/AlN heterostructures using impedance spectroscopy

Cubic gallium nitride (c-GaN) is an attractive material system for various electronic and optoelectronic device applications, as it lacks internal piezoelectric polarization fields unlike its hexagonal counterpart. Yet, the fabrication of high-performing device structures depends...
