Resistance anomaly of Nb-Si thin films
A resistance anomaly of very thin Nb–Si films is reported. The anomaly is characterized by a sudden drop in the resistance by a factor of ∼10 3 at a temperature ( T D ) of ∼180 K without any application of pressure. The lower resistance-state (∼zero Ω) is constant to 4.2 K so far as we measured. T D...
