چکیده انگلیسی
Thin films of 4-tricyanovinyl-N,N-diethylaniline (TCVA) with different thickness were prepared using thermal evaporation technique. A relative permittivity, Ér, of 3.04 was estimated from the dependence of capacitance on film thickness. The current density-voltage (J-V) characteristics of TCVA thin films have been investigated at different temperatures. At low-voltage region, the current conduction in the Au/TCVA/Au sandwich structures obeys Ohm's law. At the higher-voltage regions, the charge transport phenomenon appears to be space-charge-limited current (SCLC) dominated by an exponential distribution of traps with total trap concentration of 1.21Â ÃÂ 1022Â mâ3. In addition, various electrical parameters were determined.
