Electronic structure evolution in dilute carbide Ge $_{1 - x}$ C $_{x}$ 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 Ge $_{1 - x}$ C $_{x}$ . For ordered alloy supercells, we demon…

Broadband Phonon Scattering in PbTe-based Materials Driven Near the Ferroelectric Phase Transition by Strain or Alloying

Ronan M. Murphy, Éamonn D. Murray, Stephen Fahy +1

The major obstacle in the design of materials with low lattice thermal conductivity is the difficulty in efficiently scattering phonons across the entire frequency spectrum. Using…

Structural modification of thin Bi(1 1 1) films by passivation and native oxide model

Christian König, Stephen Fahy, James C. Greer

The structure of thin terminated Bi(1 1 1) films of approximately 1 nm thickness is investigated from first principles. Our density functional theory calculations show that covalen…
