【中文摘要】 采用真空蒸发的方法制备了PAR薄膜,研究了不同外电路参数下薄膜的电双稳特性。发现薄膜在从高阻向低阻转变时会经历一个短暂的具有非线性阻抗的中间态,并且在整个转变过程中存在一种能量效应,即当外加电压超过某一值时,完成转变所需的能量不变。 【英文摘要】 The bi-stable impedance transition under different circuit conditions of the 4-(2-pyridylazo) resorcinol (PAR) thin films, grown by vacuum deposition, was studied. A transient intermediate state with nonlinear impedance was found to exist at the interval of the high-low impedance transition of the film. Moreover,we found that at an applied voltage higher than a critical value, the energy consumption during the transition remain unchanged.
