Abstract
We have measured the electrical conductance and thermopower of a singleInSb nanowire in the temperature range from 5 to 340 K. Below temperature(T) 220 K, the conductance(G) shows a power-lawdependence on T and the current (I)–voltage (V) curve follows a power-law dependence onV at large bias voltages. These features are the characteristics ofone-dimensional Luttinger liquid (LL) transport. The thermopower(S) also shows linear temperature dependence forT below 220 K, in agreement with the theoretical prediction based on the LLmodel. Above 220 K, the power law and linear behaviours respectively in theG–T and S–T curves persist but with different slopes from those at low temperatures. The slope changescan be explained by a transition from a single-mode LL state to a multi-mode LL state.
