# RGF-electron-matlab A 100-line MATLAB code for the recursive Green's function method for electron transport ## Features * This is a simple but working code for calculating the electron transmission in the Anderson square lattice model. * This code was used to do some calculations in a review article (to be submitted). ## File organizations * A script for testing: * test_ballistic.m: calculates the transmission in the absence of Anderson disorder * The testing script calls * the driver function "find_T" to do the calculations * The driver function "find_T" calls * the "find_H" function to construct the tight-binding Hamiltonian * the "find_Sigma" function to calculate the self-energies * the "find_T1" function to calculate the transmission for a single energy point and a single disorder realization * The "find_Sigma" function calls * the "find_g00" function to calculate the surface Green's function ## Unit system * I use the following basic units: * Length: lattice constant a=1 * Energy: hopping integral t=1 ## Running the examples * Run the "test_ballistc.m" script to get the ballistic transmission in a square lattice with a width of 2. ## Contact * Zheyong Fan: brucenju(at)gmail.com
