We fabricate organic field-effect transistors (OFETs) and through the use of several device architectures, in combination with surface treatments, we were able to achieve mobilities as high as 6.8 cm2/Vs. We find that the microstrain induced in the organic semiconductor layer by the mismatch in the thermal expansion between the consecutive device layers generates trapping states and localize charge carriers, leading to a surprising universal scaling between the activation energy of the devices and the interfacial thermal expansion mismatch coefficient. en Wake Forest University charge transport field-effect transistors hybrid perovskite organic semiconductors CHARGE TRANSPORT IN ORGANIC AND HYBRID PEROVSKITE FIELD EFFECT TRANSISTORS Dissertation Jurchescu, Oana D Carroll, David L Guthold, Martin Macosko, Jed Physics 2018-05-20 open.access
