CDW transport in mesoscopic structures of submicron and nanometer scale

We have studied the CDW transport in different mesoscopic structures with s ize Variation from the micro to the nanometer scale. The structures of thre e types, all based on thin NbSe3 crystals, were investigated: 1) periodic s ystem of antidots (holes) with size and spacing variation from micron to th e submicron scale, 2) randomly distributed columnar defects (CDs) of variou s concentration with diameter of 16 nm, 3) short bridges across the conduct ing be-planes with the length of 30-50 nn. We report here a number of new f eatures of the CDW transport in mesostructures, in particular, non-linear p roperties of submicron network, the experimental evidence of quantum interf erence effect of sliding CDW on CDs threaded by magnetic flux, zero bias co nductance peak in the a*-axis transport.
