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…
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…
