The 2018 GaN power electronics roadmap

Hiroshi Amano, +64 more
- 26 Mar 2018 - 
TL;DR: This collection of GaN technology developments is not itself a road map but a valuable collection of global state-of-the-art GaN research that will inform the next phase of the technology as market driven requirements evolve.
Journal ArticleDOI

A study of dislocations in AlN and GaN films grown on sapphire substrates

TL;DR: In this paper, the dislocations in epitaxial AlN film directly grown on sapphire have been investigated by transmission electron microscope and X-ray diffraction (XRD), including direct comparison with conventional GaN film grown on the same substrate.
Journal ArticleDOI

Optical investigation of exciton localization in AlxGa1−xN

TL;DR: The optical properties of AlxGa1−xN epilayers with x ranging from 0.08 to 0.52 have been studied by photoluminescence (PL) as discussed by the authors.
Journal ArticleDOI

Greatly improved performance of 340nm light emitting diodes using a very thin GaN interlayer on a high temperature AlN buffer layer

TL;DR: In this article, a very thin GaN interlayer (10-20nm) was used as a buffer layer to prevent the penetration of dislocations in the buffer layer into the overlaying AlGaN layer.
Journal ArticleDOI

InGaN/GaN quantum wells with low growth temperature GaN cap layers

TL;DR: In this article, the use of a low growth temperature, thin GaN cap is investigated as a means to reduce indium desorption following the growth of InGaN quantum wells.
