Low Voltage Organic Field Effect Light Emitting Transistors with Vertical Geometry

The devices developed in the field of organic electronics in recent years are on the technological applications and development of organic electronic devices using organic semiconductor films. The main applications of the organic electronic revolution are; Electrochromic Device, Organic Light Emitting Diodes (OLED), Organic Field Effect Transistors (OFET). Among these devices, OLED technology has taken its place in the commercial market in the last five years and has started to be used in our daily life in a short time. The efficiency of OFET devices is related to the operation of the devices at low voltage. This is only possible if the load carriers in the channel of the OFET have a low distance. A new field of research is the ability to implement two or more features on a single device, in the construction of integrated devices. Light emitting transistors (OLEFET), where light emission and current modulation are collected in a single device, are the most intensively studied devices. In this study, ITO substrate, source and drain electrodes were made from aluminum electrode structured organic field effect OLEFETs. In the study of instead of polymer dielectric PVA, PMMA polymer material which is mostly used in OFET construction was preferred.
