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…
Machine Learning of Nonequilibrium Phase Transition in an Ising Model on Square Lattice
Dagne Wordofa, Mulugeta Bekele
This paper presents the investigation of convolutional neural network (CNN) prediction successfully recognizing the temperature of the non-equilibrium phases and phase transitions…
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…
