  1. Tight binding model of TMD

    04 Mar 2024 | | Contributor(s):: Chien-Ting Tung

    This is a Matlab code of a tight binding model of TMD materials. It uses the orthogonal sp3d5 Slater-Koster tight binding method. The code is calibrated to the MoS2 band structure shown in "V. Mishra et al., IEEE Transactions on Electron Devices, vol. 62, no. 8, pp....

  2. Empirical Tight-binding Parameterization of SmSe in the sp3d5f7s* model

    26 Mar 2013 | | Contributor(s):: Zhengping Jiang, Marcelo Kuroda, Yaohua Tan, Dennis M. Newns, Michael Povolotskyi, Timothy Boykin, Tillmann Christoph Kubis, Gerhard Klimeck, Glenn J. Martyna

    The Empirical Tight Binding(ETB) method is widely used in atomistic device simulations. The reliability of such simulations depends very strongly on the choice of basis sets and the ETB parameters.The Piezoelectronic Transistor (PET) has been proposed as a post-CMOS device for fast, low-power...

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

    18 Jan 2013 | | 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 8000 atoms are relaxed using valence force field (VFF) method, including anharmonic corrections to...
