The high-frequency mobility in disordered systems is governed by transportproperties on mesoscopic length scales, which makes it a sensitive probe forthe amount of local order. Here we present a method to measure the energydependence of the high frequency mobility by combining an electrochemicallygated transistor with in-situ quasi-optical measurements in the sub-terahertzdomain. We apply this method topoly([2-methoxy-5-(3',7'-dimethylocyloxy)]-p-phenylene vinylene) (OC_1C_10-PPV)and find a mobility at least as high as 0.1 cm^2V^-1s^-1.Comment: 3 pages (incl. 3 figures) in Appl.
