• trenches were patterned using conventional UV lithography and partially refilled with a thermally grown SiO2 layer of 130 nm. The cavity-like trench (see Figure 1b for a sketch) electrically isolates the electrodes. The process flow for the preparation of the HED-TIEs is similar to that described in [12

• exhibit a slower carrier relaxation. This can be attributed to higher electric fields and shorter charge-carrier transit times in the shorter channels of the HED-TIEs (ca. 100 nm) compared to that of OFETs (20 µm). Also the magnitude of switching in the HED-TIE device for both light and magnetic field was
