    Noise-formed triple-well potential and stochastic resonance of charge carriers

    We study the thermal dynamics of charge carriers jum** across potential traps in a one-dimensional semiconductor layer. The potential traps are denser at the middle layer and decay exponentially when moving ...

    Thermodynamics of a stochastic three level elevator model

    We study the thermodynamic properties of a single particle occupying one of three available energy levels in a non-equilibrium regime. The particle is thermally coupled to a classical Maxwell-Boltzmann thermal...

    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...

    Stochastic resonance of charge carriers diffusing in a nonhomogeneous medium with nonhomogeneous temperature

    We investigate the dynamics of charge carriers hop** from one trap to the other trap along an n-type semiconductor layer consisting of a spatially nonhomogeneous trap distribution of depth Φ assisted by thermal...
