Abstract

In an unpublished disclosure, we reported observations of the nonlinearity of the voltage-current characteristics of thermistors† at 4.2°K. By using an ac technique in which the voltage across the element was displayed on an oscilloscope as a function of the current through the element, the curvature of the characteristics was demonstrated. The ratio of the ordinate of a point on the curve to its abscissa defines the resistance R dc, which would be observed by a dc measuring technique at the chosen conditions of current or voltage. The dependence of R dc on applied voltage, computed from the characteristics shown in Fig. 1, is given in Fig, 2.
