Interfacial Modification in Organic Thin Film Transistors with OTS Solutions

Organic materials are generally used in many electrical devices like light emitting diodes thin film transistors, and photo-detectors. Due to variety of materials, fabrication methods, and amazing characteristics, more and more researchers are devoted to the research of organic electrical devices. For organic thin film transistors, many different materials, structures, and special modification methods were used to improve the characteristics of devices. Nowadays, the characteristics of OTFT were almost the same as amorphous silicon (a-Si) which was commonly adapted in the modern liquid crystal display (LCD). In this report, octadecyltrichlorosilane (OTS) with toluene as solvent was used to modify the interface of organic and dielectric layers in OTFT.
