Abstract
An n-well ion-implanted resistor is shown to work as a very-linear high-gain photodetector at 4.2 K. We take advantage of freeze-out and light-assisted carrier ionisation effects to create a photodetector with a current-gain factor G from 1x104 to 1.6x106. Experimental results show that at the current gain of 1.6X106, excellent linearity in optical response is obtained when the resistor is illuminated with a red-light source.
