Abstract

The two CDW energy gaps of NbSe₃were measured by means of the point contact tunneling technique. The peak to peak values of energy gaps at T=4.2K areƃtypically 2ख_H蝱180 mV and 2ख_L蝱73 mV from the NbSe₃-Au junction, where ख_Hand ख_Lcorrespond to the higher CDW transition temperature T_H=145K and lower one T_L=59K, respectively. From these values, we obtained that 2ख_H/kT_H=14.4 and 2ख_L/kT_L=14.3, which are much larger than the DCS value.
