Disorder into Correlation: A Microscopic Mechanism for Sub-McIntyre Avalanche Noise
Shafat Shahnewaz, Hannaneh Karimi, Joe C. Campbell +1
Avalanche multiplication is intrinsically stochastic, yet experiments reveal excess noise below the minimum predicted by McIntyre's local-field theory. The microscopic origin of th…
A transferable full-band Monte Carlo framework for complex alloy avalanche photodiodes
Shafat Shahnewaz, Hannaneh Karimi, Joe C. Campbell +1
We present a physics-based multiscale full-band Monte Carlo framework for modeling avalanche multiplication and excess noise in complex alloy avalanche photodiodes (APDs), demonstr…
A Matrix Quantum Kinetic Treatment of Impact Ionization in Avalanche Photodiodes
Sheikh Z. Ahmed, Shafat Shahnewaz, Samiran Ganguly +2
Matrix based quantum kinetic simulations have been widely used for the predictive modeling of electronic devices. Inelastic scattering from phonons and electrons are typically trea…
Breaking of general rotational symmetries by multi-dimensional classical ratchets
A. W. Ghosh, S. V. Khare
We demonstrate that a particle driven by a set of spatially uncorrelated, independent colored noise forces in a bounded, multidimensional potential exhibits rotations that are inde…
