Abstract :
This paper introduces an analysis and simulation of electron transport in accumulation layers from 300 K down to 4.2 K. The analysis, modeling, and simulation are confirmed with experimental results of an n-well gated resistor. The doping and gate oxide thickness dependence of the thickness of the accumulation layer is also analyzed and simulated. A model that accounts for all these variables is presented. The simulations are performed with PISCES, MINIMOS-NT, and a proprietary simulator. At 4.2 K a quasi-CMOS circuit is validated with a simple gated resistor
