Amorphous phases of Mo and Nb which are stable at room temperature have been obtained by e‐beam vapor deposition of the metals in a partialN2atmosphere on substrates kept below 100K. The structure of these films can be described in terms of the DRPHS model. The amorphous Mo‐films show a large increase in the superconducting transition temperature (compared to bulk Mo) whileTof amorphous Nb films decreases. For the most homogeneous Mo1−xNxfilms theTcobtained is near 8.5K and the transition width is ≲0.1K. In the absence of a nitrogen atmosphere pure Mo‐films, vapor quenched onto sputter cleaned substrates at 4.2°K are found to be crystalline bcc. Contamination appears to stabilize amorphous or other nonequilibrium crystalline phases (fcc, hcp).
