Trap density in conducting organic semiconductors determined from temperature dependence of J-V characteristics

Space charge limited currents in organic semiconductors are frequently observed to obey the power law J-V-m and are attributed to an exponential distribution of traps having two parameters, namely the characteristic distribution energy E-t and the trap concentration H-t. We determine these parameters from the J(V) characteristics at two or more temperatures reported in literature. (C) 2003 American Institute of Physics.
