TECHNOLOGIES OF PREPARATION OF ULTRATHIN FILMS FOR ORGANIC ELECTRONICS

Аннотация

The development of organic electronics has necessitated the advancement of ultrathin film fabrication techniques to achieve high-performance devices such as organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and organic field-effect transistors (OFETs). This paper reviews the most prominent methods for preparing ultrathin films, including Langmuir-Blodgett deposition, spin coating, dip coating, layer-by-layer assembly, and vacuum thermal evaporation. Each technique was evaluated in terms of film uniformity, thickness control, scalability, and compatibility with organic materials. Special emphasis was placed on optimizing film morphology and interfacial properties to enhance charge transport and device efficiency.
