Abstract:
|
Thin film transistors based on polyarylamine poly?N,N?-diphenyl-N,N
?bis?4-hexylphenyl?-
?1,1?biphenyl?-4,4?-diamine ?pTPD? were fabricated using spin coating in order to measure the
mobility of pTPD upon oxidation. Partially oxidized pTPD with a molecular magnetic cluster
showed an increase in mobility of over two orders of magnitude. A transition in the mobility of
pTPD upon doping could also be observed by the presence of a maximum obtained for a given
oxidant ratio and subsequent decrease for a higher ratio. Such result agrees well with a previously
reported model based on the combined effect of dipolar broadening of the density of states and
transport manifold filling. |
