Noise-Activated Dopant Dynamics in Two-Dimensional Thermal Landscapes with Localized Cold Spots

Mesfin Taye, Yoseph Abebe, Tibebe Birhanu +2

Controlling dopant transport with high spatial precision is crucial for improving the semiconductor functionality, reliability, and scalability. Although prior models of noise-assi…

Noise-created bistability and stochastic resonance of impurities diffusing in a semiconductor layer

Mesfin Asfaw, Berhanu Aragie, Mulugeta Bekele

We investigate the dynamics of impurities walking along a semiconductor layer assisted by thermal noise of strength and external harmonic potential . Applying a nonhomoge…

Competing jump cycles for vacancy diffusion in binary alloys

Zerihun Getahun, Mesfin Asfaw, Mulugeta Bekele

The mean-first-passage-times (MFPTs) for a vacancy that diffuses (via one- and six-jump cycles) in a two dimensional ordered binary alloy are evaluated using the properties of rand…

Exploring the operation of a tiny heat engine

Mesfin Asfaw, Mulugeta Bekele

We model a tiny heat engine as a Brownian particle that moves in a viscous medium in a sawtooth potential (with or without load) assisted by placed hot and cold…

Energetics of a simple microscopic heat engine

Mesfin Asfaw, Mulugeta Bekele

We model a microscopic heat engine as a particle hopping on a one-dimensional lattice in a periodic sawtooth potential, with or without load, assisted by the thermal kicks it gets…
