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…
First principles analysis of electronic structure evolution and the indirect- to direct-gap transition in GePb group-IV alloys
Christopher A. Broderick, Edmond J. O'Halloran, Eoin P. O'Reilly
We present a theoretical analysis of electronic structure evolution in the group-IV alloy GePb based on density functional theory. For ordered alloy supercells we dem…
Electronic structure of semiconductor nanostructures: A modified localization landscape theory
D. Chaudhuri, J. C. Kelleher, M. R. O'Brien +2
In this paper we present a modified localization landscape theory to calculate localized/confined electron and hole states and the corresponding energy eigenvalues without solving…
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…
