Summary: | Organic devices are advantageous in term of high carrier mobility, lightweight and flexibility. The solution processed method offers economic and efficient device fabrication in small laboratory scale. The α-quaterthiophene (α-4T) is an oligomer and a p-type organic semiconductor. In this study, pure α-4T and polylactide acid (PLA)/α-4T films were spin-coated on glass and indium tin oxide (ITO) substrates at low spin frequency. The hydrated films were left to dry at room temperature and later in vacuum oven. The α-4T microstructures changed when blended with the polymer. The roughness of the 180 nm ITO film was found to be 1 - 30 nm and the organic layer formed uneven thickness (max ~ 300 nm) thicker toward the edge. The preparation of spin coated organic thin film is the first step towards realizing solution processed organic device in electronic packaging. |
