چکیده انگلیسی
We have investigated the differential conductance of point contact that is formed by Pt wire and (2¯ 01) plane of the quasi-one-dimensional blue bronze K0.3MoO3 down to Tâ¼40K. Below Tâ¼70K, that temperature is well lower than the charge-density wave (CDW) transition temperature TCDW=180K, we found the double gaps like structure that becomes definite with decreasing temperature. From the singularities of the structure, the energy gaps are estimated as 2Î1â¼112meV and 2Î2â¼60meV, respectively. It is suggested that the structure is affected to the imperfect nesting of the Fermi surfaces. Both the two- and three-dimensionality would play important role in the electronic system of K0.3MoO3.
