Development of organic light emitting devices sensible to magnetic field application and organic field effect transistors operate at low voltage

Abstract

The organic electronics became in the last years an interesting area, since fundamental research until practical applications in optoelectronic devices, as soon, arising new challenges mainly with relation of new physical properties of organic materials and consequently technological advances. This project is based in the study of two different devices: light emitting devices and field effect transistors using conjugated polymers or low molecular weight molecules as active layers. The objective for organic light emitting devices is the study of changes in electrical properties by magnetic field application that modify the efficiency of light emitting conversion, for field effect transistors, in the first step, will be study the interfacial properties by metal-insulator-organic semiconductor capacitor, for using of AC methods as admittance spectroscopy to obtain the insulator/semiconductor interface characteristics, this characterization is very important to better materials choice to made transistors working at low voltages, that is a challenge in organic electronics.
