    The role of external single-well potential, spatially varying temperature, spatially varying trap potential and time varying force on the impurity dynamics

    In this paper, we study the role of external parabolic potential, spatially varying temperature, spatially varying trap potential, and time-varying weak signal on the impurities walking from one lattice site t...

    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...
