- 論文の詳細を見る
Current–voltage ($I$–$V$) curves were studied for the quantum point contacts (QPCs) of gold, platinum, silver and copper at room temperature. Nonlinear $I$–$V$ curves of a cubic function, $I=aV+cV^{3}$, were found for all QPCs, that were fabricated between a cleaned Scanning Tunneling Microscope (STM) tip and a cleaned substrate in an ultrahigh vacuum. The nonlinear parameter $c/a$ was found to be positive, and scattered in the range of ${\sim}0$ to 1 [1/V2] independent of the conductance at the zero-bias voltage. The average value of $c/a$ showed no strong dependence on the metal elements.
