  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...
