Carbon Coater, Pulsed Laser deposition, Sputter Coater, Thermal evaporation
Electronic components based on thin-film organic semiconductors have many applications because of their flexibility and large-scale fabrication at low cost. These semiconductors allow the creation of electronic devices such as OFET (Organic-Field Effect Transistor), OLED (Organic-Light Emitting Diode) and OPV (Organic Photovoltaic Cell) as a new generation of electronics. The electronic properties of the organic molecules depend on the bonds between the atoms. The location and properties of these interatomic bonds determine how light is absorbed and the charge transferred by molecules. The most important of these bonds are the conjugated bonds and how they are joined inside the molecules, where the shared electrons are able to move part of the molecule.
