Abstract
Thin films of 4-tricyanovinyl-
N,
N-diethylaniline (TCVA) with different thickness were prepared using thermal evaporation technique. A relative permittivity,
ɛ
r, 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 1.21
