Description

In solid-state physics, the electronic band structure of a solid describes ranges of energy that an electron is "forbidden" or "allowed" to have. It is a function of the diffraction of the quantum mechanical electron waves in the periodic crystal lattice with a specific crystal system and Bravais lattice. The band structure of a material determines several characteristics, in particular its electronic and optical properties. More information on Band structure can be found here.

  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....

    ninithi which is a free and opensource modelling software, can be used to visualize and analyze carbon allotropes used in nanotechnology. You can generate 3-D visualization of Carbon nanotubes, Fullerenes, Graphene and Carbon nanoribbons and analyze the band structures of nanotubes and graphene.

  4. Bulk Bandstructure in MATLAB: Pseudopotential Method

    08 Feb 2010 | | Contributor(s):: Muhanad Zaki

    This code (MATLAB) readily calculates and plots the bandstructure of Silicon (bulk) using the empirical pseudopotential method.Detailed instructions are in the compressed archive.I hope it would be a useful/interesting educational toolNote: If you are running this code in a non-Windows OS (e.g....

  5. ECE 539 Report: Study of two-dimensional Shrodinger-Poisson Solver

    01 Jun 2009 | | Contributor(s):: Fawad Hassan

    We solve the 2-Dimensional Shrodinger-Poisson system of equations using a self consistent scheme (like Gummel Iteration). We study a double gate Silicon Mosfet oriented in the 100 direction using the above setup. We assume a simple 6-valley bandstructure for Silicon.
