Fully analytic valence force fields for the relaxation of group-IV semiconductor alloys: elastic properties of group-IV materials calculated from first principles

Daniel S. P. Tanner, Christopher A. Broderick, Amy C. Kirwan +2

Si $_{y}$ Ge $_{1 - x - y}$ (C,Sn,Pb) $_{x}$ alloys have attracted significant attention as a route to achieve a direct-gap group-IV semiconductor. Using density functional theory (DFT) - e…

Impact of band-anticrossing on band-to-band tunneling in highly-mismatched semiconductor alloys

Sarita Das, Christopher A. Broderick, Eoin P. O'Reilly

We theoretically analyse band-to-band tunneling (BTBT) in highly-mismatched, narrow-gap dilute nitride and bismide alloys, and quantify the impact of the N- or Bi-induced perturbat…

Impact of stoichiometry and strain on Ge $_{1 - x}$ Sn $_{x}$ alloys from first principles calculations

Conor O'Donnell, Alfonso Sanchez-Soares, Christopher A. Broderick +1

We calculate the electronic structure of germanium-tin (Ge $_{1 - x}$ Sn $_{x}$ ) binary alloys for $0 \leq x \leq 1$ using density functional theory (DFT). Relaxed alloys with semicondu…
