Hot Phonon Bottlenecks and the Role of Non-Equilibrium Acoustic Phonons in III-V Multi-Quantum Well Systems
Izak Baranowski, Dragica Vasileska, Ian R. Sellers +1
The hot phonon bottleneck effect is a promising mechanism for the realization of a true hot carrier solar cell. Prior work has assumed that the acoustic phonons created via decay o…
Spatial profiles of photon chemical potential in near-field thermophotovoltaic cells
Dudong Feng, Eric J. Tervo, Dragica Vasileska +3
Emitted photons stemming from the radiative recombination of electron-hole pairs carry chemical potential in radiative energy converters. This luminescent effect can substantially…
Defect State Density and Orbital Localization in a-Si:H/c-Si Heterojunction and the Role of H
Reza Vatan Meidanshahi, Stephen M. Goodnick, Dragica Vasileska
In this paper, we explore the effect of H and its bonding configurations on the defect state density and orbital localization of hydrogenated amorphous Si (a-Si:H)/crystalline Si (…
Feasibility, Accuracy and Performance of Contact Block Reduction method for multi-band simulations of ballistic quantum transport
Hoon Ryu, Hong-Hyun Park, Mincheol Shin +2
Numerical utilities of the Contact Block Reduction (CBR) method in evaluating the retarded Green's function, are discussed for 3-D multi-band open systems that are represented by t…
Diffusive Transport in Quasi-2D and Quasi-1D Electron Systems
I. Knezevic, E. B. Ramayya, D. Vasileska +1
Quantum-confined semiconductor structures are the cornerstone of modern-day electronics. Spatial confinement in these structures leads to formation of discrete low-dimensional subb…
Electron mobility in silicon nanowires
E. B. Ramayya, D. Vasileska, S. M. Goodnick +1
The low-field electron mobility in rectangular silicon nanowire (SiNW) transistors was computed using a self-consistent Poisson-Schrödinger-Monte Carlo solver. The behavior of the…
