A Computer Controlled Automatic System for Measuring the Conductivity and Hall Effect in Semiconducting Samples
Abstract
A unique computer controlled automatic system for measuring the conductivity and Hall effect in semiconducting samples is described. The system features a small process control computer which runs a temperature programmable liquid helium Dewar, a magnet, and a data acquisition system. Fifty temperature points can be preprogrammed in any desired distribution over the range 4.2–400 K. The control computer ensures that the system is virtually …
