| 中文摘要 | frequency-dependent electrical transport properties of 4, 4', 4''-tri(n-carbazolyl)-triphenylamine (tcta) are analyzed by impedance spectroscopy (is) as functions of bias and temperature. the cole-cole plot shows a single semicircle which indicates that the equivalent circuit can be designed as a single parallel resistor r(p) and capacitor c(p) network with a series resistance r(s) the bulk capacitance c(p) remains unchanged while the resistance r(p) decreases along with bias voltage. conduction mechanism matches well with the space-charge-limited current (sclc) model with exponential trap charge distributions. the temperature-dependent impedance studies reveal the activation energy of 0.246 ev with no phase change in the temperature range 220-320 k. these results indicate that the is method is applicable for organic semiconductors having a wide band gap. |
