【摘要】 从31种TCNQ离子自由基盐的粉末压片中,观察到Li-TCNQ、Mn（TCNQ）₂·3H₂O、Cu-TCNQ、Cu（TCNQ）₂、Zn（TCNQ）₂·xH₂O和Ag-TCNQ有电开关效应.粉末压片的直径是5或8mm,厚度300—600um,片的两面分别蒸镀Cu和Al电极.电压超过阈值5-8V时,伏安特性出现突变,电阻值突然下降,从10⁴-10⁵Ω降至10²-10³Ω.高阻态（关态）与低阻态（开态）的电阻比值约几十到几千.更多还原

【Abstract】 Among 31 TONQ- ion-radical salts, electrical switching has been observed in powder compactions of Li-TONQ, Mn(TONQ)2.3H2O, Cu-TCNQ, Cu(TCNQ)2, Zn(TONQ)2.xH2O and Ag-TONQ. These TONQ- ion-radical salt powder compactions were of 5 or 8mm diameter and approximately 300-600 um in thickness with evaporated On and Al electrodes. The current-voltage characteristics revealed an abrupt decrease in resistance from 104-105 to 102-103 at a threshold voltage of 5-8 V. The ratio of Bott/Bon is tens to thousand times.更多还原
