EFFECT OF PRESSURE AND ELECTRIC FIELD ON CDW INDUCED RESISTIVITY ANOMALIES IN NbSe3

Abstract

We report the effect of pressure on the two resistivity anomalies at 145 K and 59 K in NbSe3 and resulting from charge density wave formation. The rate of decrease of the critical temperature with pressure is the same at both transitions (dT/dp = 4 K/kbar). We observe also the suppression by electric fields of these two anomalies, which we attribute to Zener breakdown across extremely small gaps introduced by the CDW
