Impact Ionization and Hot-Electron Injection Derived Consistently from Boltzmann Transport [PDF]

open access: yes, 1998
We develop a quantitative model of the impact-ionizationand hot-electron–injection processes in MOS devices from first principles. We begin by modeling hot-electron transport in the drain-to-channel depletion region using the spatially varying Boltzmann ...

Temperature Dependence Study of Electrical and Electro-Optical Performances of Midwave Infrared Ga-Free T2SL Barrier Photodetector

open access: yesApplied Sciences, 2022
In this paper, we report on temperature dependence performances of a midwave infrared (MWIR) Ga-free InAs/InAsSb type-II superlattice (T2SL) barrier (XBn) photodetector grown by molecular beam epitaxy on n-type GaSb substrate.

Intrusion and extrusion of water in hydrophobic nanopores [PDF]

open access: yes, 2017
Heterogeneous systems composed of hydrophobic nanoporous materials and water are capable, depending on their characteristics, of efficiently dissipating (dampers) or storing ("molecular springs") energy.

Polarization-Engineering in III-V Nitride Heterostructures: New Opportunities For Device Design [PDF]

open access: yes, 2010
The role of spontaneous and piezoelectric polarization in III-V nitride heterostructure devices is discussed. Problems as well as opportunities in incorporating polarization in abrupt and graded heterojunctions composed of binary, ternary, and quaternary

Yield, Area and Energy Optimization in Stt-MRAMs using failure aware ECC

open access: yes, 2016
Spin Transfer Torque MRAMs are attractive due to their non-volatility, high density and zero leakage. However, STT-MRAMs suffer from poor reliability due to shared read and write paths.

The influence of Vehicle Dynamics Control System on the Occupant’s Dynamic response during a Vehicle collision [PDF]

open access: yes, 2012
This paper aims to apply a vehicle dynamics control system to mitigate a vehicle collision and to study the effects of this systems on the kinematic behaviour of the vehicle's occupant. A unique three-degree-of-freedom vehicle dynamics-crash mathematical
