Simulation Study of Non-Quasi Static Behaviour of MOS Transistors

Kumar D.V., Thakker R.A., Patil M.B., Rao V.R., Indian Institute of Technology - Bombay, IN

In this paper, we study the "non-quasi static" (NQS) behaviour of MOS transistors using an exact quasi static Look-up Table (LUT) [1] MOSFET model implemented in a general-purpose circuit simulator SEQUEL [2], device simulator ISE-TCAD [...]

A New Lateral Trench Sidewall Schottky (LTSS) Rectifier on SOI

Singh Y., Kumar M.J., Indian Institute of Technology, IN

In this paper, a new Schottky rectifier structure, called Lateral Trench Sidewall Schottky (LTSS) rectifier on SOI is presented. Based on two-dimensional simulations, we demonstrate that the proposed device is superior in performance as compared [...]

A Signal Processing Approach for the Analysis of Mechanism of Surface Generation in EDM

Murti V.S.R., Laxminarayana P., Reddy M.K., Osmania University, IN

For a superior analysis of mechanism of erosion and surface generation in EDM, the surface profile is analysed using a signal analysis technique namely its autocorrelation function. The correlation length thus evaluated and the roughness [...]

Time Series Modelling of Surface Topography Generated by Ultrasonic Machining Process

Murti V.S.R., Naga Prasada Rao B., Krishna Reddy M., Osmania University, IN

In these studies the surface roughness profiles were modelled and analysed for a better understanding of the mechanism of metal erosion in USM. Different materials were selected for this purpose based on their diverse properties [...]

Modelling of Atmosphere Sensitive Heterojunctions for Device Applications

Mangamma G., Gnanasekaran T., Indira Gandhi Centre For Atomic Research, IN

Simple and inexpensive methods of detecting pollutants in ambients are needed for maintenance of safe environment in modern industries. Chemical sensors based on catalytic combustion and using solid state electrolytes and semiconducting oxides etc. are [...]

Study of Well Barrier Hole Burning in Quantum Well Bistable Lasers

Ganesh Madhan M., Vaya P.R., Gunasekaran N., Anna University, IN

Quantum carrier capture and release effects on optical bistability in multiple quantum well (MQW) lasers are studied using the well barrier hole burning model. The ratio of carrier capture to release time (h) is varied [...]

Study of Voltage Tunable Asymmetric Quantum Well Structure for Infrared Detection

Vaya P.R., Ananda Natarajan S., Srinivasan K.R., Indian Institute of Technology, IN

The performance of GaAs/AlGaAs asymmetric quantum well infrared detectors exhibiting inter subband absorption has been studied. The asymmetric quantum well structure considered for the present study consists of two regions, a step quantum well with [...]
