Title: The potential of ScN-GaN heterojunctions and alloys for wide bandgap semiconductor devices and displays

Abstract

The wide bandgap semiconductor GaN and its solid solution alloys with InN and AlN are of increasing interest for a number of optoelectronic applications. Current, the potential for combining GaN with ScN, a rock salt structure semiconductor with an optical bandgap of {approximately} 2.1 eV, has not been well recognized. To explore the idea, in this conceptual paper the authors first critically review the existing knowledge on ScN, including the controversies regarding stoichiometry/dopability and whether it is a semiconductor or a semimetal. They then propose three concepts for enhancing the potential of GaN in optoelectronic applications. The first is to combine GAN with ScN to form lattice matched GaN-ScN heterojunctions, the second is to form GaN-ScN solid solution alloys covering the range of energy gaps from 2.1--3.4 eV, and the third is to introduce rare earth luminescent centers into heterojunctions and alloys. 51 refs., 6 figs., 2 tabs.
