摘要We study the temperature dependence of the conductivity of the two-dimensional (2D) electronic solid. In realistic samples, a domain structure forms in the solid and each domain randomly orients in the absence of the in-plane field. At a higher temperature, the electron transport is governed by thermal activation form of sigma(xx)(T)proportional toe(0)(-Delta)/k(B)T. The impurities will localize the electron states along the edges of the crystal domains. At a sufficiently low temperature, another transport mechanism, called Mott's variable range hopping mechanism-similar to that in a disorder insulator-takes effect. We show that as the temperature decreases, a crossover from the fixed range hopping of the transport to the variable range hopping of transport in the 2D electron system may be experimentally observed.
