    Thermally activated diffusion of impurities along a semiconductor layer

    The dynamics of impurities that walk along a semiconductor layer assisted by thermal noise strength and quartic potential is explored analytically and numerically. Applying two cold spots in the vicinity of th...

    Impurity diffusion in a harmonic potential and nonhomogeneous temperature

    We propose different ways of manipulating the dispersion of impurities along a semiconductor layer during heat treatment. The impurities undergo a random walk assisted by a nonlinear harmonic potential and non...
