Structural and electrical properties of evaporated Cr-Ni films as a function of gas pressure
L. Lassak,K. Hieber +1 more
TL;DR: In this article, it was shown that at an oxygen partial pressure of 1 x 10-6 torr the TCR became negative and that the films had a structure corresponding to a distorted b.c. Cr lattice, which did not change even after annealing for several hours at 300 °C.
Journal ArticleDOI
Structural and electrical properties of chromium and nickel films evaporated in the presence of oxygen
K. Hieber,L. Lassak +1 more
TL;DR: In this article, the negative temperature coefficient of resistivity (TCR) is caused by small amounts of an amorphous oxide surrounding the metal crystals, and it is shown that when Ni is evaporated in the presence of oxygen, the TCR changes from positive to negative values at about 5 × 10-5 torr.
