Abstract : In the last decades, the interest in the nanowires has increased. The properties of the nanowires can be controlled by choosing the type of the material that used in their synthesis and the method of synthesis. The transmission coefficients of an electron scattered by the Gaussian potential were calculated in one- and two-dimensional nanowire by using the Wigner-Eisenbud functions and the R-matrix method. The cylindrical coordinates are considered in the two-dimensional case. The Gaussian potential was applied in the scattering region. The scattering region was doped by Aluminum Gallium Arsenide (AlGaAs). There is a positive relationship between the transmission probabilities and the incident energy of an electron, that means the transmission coefficients are energy dependent. The transmission coefficients are increasing as the high/depth of the Gaussian potential decreases. There is a reverse relationship between the amplitudes (oscillating) of the transmission curves and the transmission coefficients. We show in this research, in details, the transmission coefficient behavior in different cases.
