| 英文摘要 | The electron transport properties of bis[2-(2-hydroxyphenyl)-pyridine]beryllium (Bepp(2)) are investigated by impedance spectroscopy over a frequency range of 10 Hz to 13MHz. The Cole-Cole plots demonstrate that the Bepp(2)-based device can be represented by a single parallel resistance R-p and capacitance C-p network with a series resistance R-s. The current-voltage characteristics and the variation of R-p with applied bias voltage indicate the electron conduction of space-charge-limited current with exponential trap distributions in Bepp(2). It can be seen that the electron mobility exhibits strong field-dependence in low electric field region and almost saturate in high electric field region. It is experimentally found that Bepp(2) shows dispersion transport and becomes weak as the electric field increases. The activation energy is determined to be 0.043 eV by temperature-dependent conductivity, which is consistent with the result obtained from the temperature-dependent current density characteristics. The electron mobility reaches the orders of 10(-6)-10(-5) cm(2) V-1 s(-1), depending on the electric field. (C) 2014 AIP Publishing LLC. |
