Multiple longitudinal potential barriers affect electron transport in a nanostructure. In addition to a symmetric, aperiodic quantum wire with five potential barriers, a quantum wire containing thirteen potential barriers was modeled based on a quasiperiodic sequence known as the Fibonacci sequence. Conductance of the wires and transmission coefficients of the corresponding one-dimensional systems were calculated and analyzed in this work.Conductance calculations were performed using a FORTRAN computer program, tbgf, which performs the tight-binding, recursive Green's function method. Also Program Tran Coeffwas developed in order to calculate one-dimensional transmission coefficients using the method known as wavefunction matching. This method matches electronic wavefunctions in neighboring regions to determine the one-dimensional transmission coefficients at the electron energy normalized to the barrier strengths. The program uses the data file generated by Program Data Input. / Department of Physics and Astronomy
