Consequently, a novel LC-OFET was fabricated using a nematic liquid crystal (E63) and a P3HT mixture in an OFET cell. Cell thickness was determined through field emission scanning electron microscopy. For assessment of the electrical characteristics, the LC-OFET device was exposed to various UV light intensities in total darkness for the purpose of obtaining the output- and transfer-current voltage. The capacitance-frequency plot of the capacitor cell was then measured to determine the main parameters including the threshold voltage (V-Th), field effect mobility ((FET)) and current on/off ratio (I-on/off) of the device. Thus, the full characterisation and UV light response of the electronic parameters were determined for this new class of transistors. Results showed that the new LC-OFET exhibited good performance in the form of low V-Th, high(FET), and high I-on/off.en10.1080/14786435.2016.1200200info:eu-repo/semantics/closedAccessPhoto induced effectliquid crystalsanisotropymobilityorganic materialsLC-OFETOFETdipoleArticle962223622371WOS:000380160400004Q3Q2
