Nowadays, the development of VLSI technology is mainly directed towards the miniaturization of semiconductor devices which in turn is heavily dependent on the advancement in the CMOS technology. The minimum dimension of a single device for present day technology is below sub-100 nm in channel length. As CMOS technology dimensions are being aggressively(More)
INTRODUCTION Exposure to the confined hyperbaric, hyperoxic environment of the saturation chamber poses a number of unique physiological challenges to divers. Appropriately tailored training, nutrition and health programs may help support the body to cope with and overcome these challenges. AIM To describe the self-reported habits and attitudes of(More)
Millimeter and sub-millimeter wave response of two-dimensional hot electrons in double delta doped GaAs quantum well is studied here incorporating deformation potential acoustic, polar optic, ionized background and remote impurity scatterings in the framework of heated drifted Fermi-Dirac distribution function. The inclusion of delta doping is found to(More)
Particle Swarm Optimization (PSO) Algorithm is employed to determine the optimized system parameters of modulation doped Al<sub>x</sub>Ga<sub>1-x</sub>As/GaAs quantum well for better low-power and high frequency response. The mobility (ac and dc) of two-dimensional hot electrons in square quantum well of Al<sub>x</sub>Ga<sub>1-x</sub>As/GaAs is computed(More)
A simple analytical model of a nanoscale fully depleted dualmaterial gate (DMG) SOI and SON MOSFETs has been developed and their performance comparison analysis is presented in this paper. An analytical model for the surface potential and threshold voltage has been developed both for these structures using a generalized 2D Poisson’s equation solution. The(More)
The workhorse of the present electronics industry, silicon MOSFET, is having a unique attribute; its logic characteristics improve as its dimensions are reduced. Without further reductions in operating voltage, future scaling may not be feasible. One possible solution is to introduce a new channel material in which charge carriers travel at a much higher(More)
Small-signal ac transport of degenerate two-dimensional hot electrons in PbTe quantum wells is studied here incorporating deformation potential acoustic, polar optic and ionized background and remote impurity scatterings in the framework of heated drifted Fermi-Dirac distribution. The effects of double delta doping on millimeter and sub-millimeter wave(More)
The upcoming trend in VLSI technology has led to the miniaturization of semiconductor devices which in turn is strongly dependent on the advancement in the CMOS technology. The present technology is below sub-100 nm in channel length which is the minimum dimension of single device. As CMOS technology dimensions are being intrusively scaled down to the(More)
