Journal ArticleDOI
Electron-beam-induced strain within InGaN quantum wells: False indium “cluster” detection in the transmission electron microscope
TL;DR: In this paper, high-resolution TEM images acquired immediately after first irradiating a region of quantum well indicates no gross fluctuations of indium content in the InGaN alloy, during only a brief period of irradiation, inhomogeneous strain is introduced in the material due to electron beam damage.
Journal ArticleDOI
Critical thickness calculations for InGaN/GaN
TL;DR: In this paper, a model based on the overall energy balance was used to calculate the critical thickness for an InGaN epitaxial layer on a GaN substrate, which was found to be lower than values predicted by models proposed by Fischer or People and Bean.

Journal ArticleDOI
Optical and microstructural studies of InGaN∕GaN single-quantum-well structures
Darren M. Graham,A. Soltani-Vala,Phil Dawson,M. J. Godfrey,Tim Michael Smeeton,Jonathan S. Barnard,Menno J. Kappers,Colin J. Humphreys,Ej Thrush +8 more
TL;DR: In this paper, the Huang-Rhys factor extracted from the Fabry-Perot interference-free photoluminescence spectra has been compared with the results of a model calculation, yielding a value of approximately 2nm for the in-plane localization length scale of carriers.
Journal ArticleDOI
Carrier localization mechanisms in InxGa1?xN/GaN quantum wells
Duncan Watson-Parris,M. J. Godfrey,Philip Dawson,Rachel A. Oliver,M. J. Galtrey,Menno J. Kappers,Colin J. Humphreys +6 more
TL;DR: In this paper, the authors calculated the localization lengths of the electrons and holes in InGaN/GaN quantum wells using numerical solutions of the effective mass Schrodinger equation.
