  1. Bismide Semiconductors: Revolutionising Telecom Lasers

    19 Oct 2015 | Papers | Contributor(s): Muhammad Usman, Christopher A Broderick, Eoin P O'reilly

    Today’s telecomm lasers are plagued with Auger-related losses, which significantly reduce their efficiency and make device cooling essential. We are proposing a radical change in the laser...


  2. Electronic Structure Theory of Dilute Impurity Alloys: GaBiP and GaBiAs

    18 Jan 2013 | Online Presentations | Contributor(s): M. Usman

    We report an atomistic model established for electronic structure calculations of GaBiAs (0 < Bi < 12%) alloys based on empirical tight binding parameters. Alloy supercells consisting of 1000 and...
