Polar InGaN/GaN quantum wells: Revisiting the impact of carrier localization on the green gap problem
Daniel S. P. Tanner, Philip Dawson, Menno J. Kappers +2
We present a detailed theoretical analysis of the electronic and optical properties of c-plane InGaN/GaN quantum well structures with In contents ranging from 5% to 25%. Special at…
Electronic structure evolution in dilute carbide GeC alloys and implications for device applications
Christopher A. Broderick, Michael D. Dunne, Daniel S. P. Tanner +1
We present a theoretical analysis of electronic structure evolution in the highly-mismatched dilute carbide group-IV alloy GeC. For ordered alloy supercells, we demon…
Fully analytic valence force field model for the elastic and inner elastic properties of diamond and zincblende crystals
Daniel S. P. Tanner, Miguel A. Caro, Stefan Schulz +1
Using a valence force field model based on that introduced by Martin, we present three related methods through which we analytically determine valence force field parameters. The m…
Comparison of first principles and semi-empirical models of the structural and electronic properties of GeSn alloys
Edmond J. O'Halloran, Christopher A. Broderick, Daniel S. P. Tanner +2
We present and compare three distinct atomistic models -- based on first principles and semi-empirical approaches -- of the structural and electronic properties of GeSn$_{x…
Hybrid functional study of non-linear elasticity and internal strain in zincblende III-V materials
Daniel S. P. Tanner, Miguel A. Caro, Stefan Schulz +1
We investigate the elastic properties of selected zincblende III-V semiconductors. Using hybrid functional density functional theory we calculate the second and third order elastic…
Random alloy fluctuations and structural inhomogeneities in -plane InGaN quantum wells: theory of ground and excited electron and hole states
Daniel S. P. Tanner, Miguel A. Caro, Eoin P. O'Reilly +1
We present a detailed theoretical analysis of the electronic structure of -plane InGaN/GaN quantum wells with indium contents varying between 10\% and 25\%. The electronic struc…
