We have investigated the differential conductance of point contact that is formed by Pt wire and ((2) over bar 01) plane of the quasi-one-dimensional blue bronze K0.3MoO3 down to T similar to 40 K. Below T similar to 70 K, that temperature is well lower than the charge-density wave (CDW) transition temperature T-CDW = 180 K, 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 2 Delta(1) similar to 112 meV and 2 Delta(2) similar to 60 meV, 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 K(0.3)Moo(3). (C) 2012 Elsevier B.V. All rights reserved.
