Research

 We intend to investigate several key processes which includes nucleation and growth of poly(3-hexyl thiophene) (P3HT) by self‐seeding technique in which the crystal number density, their sizes and level of perfection are under control. Polymer chains have a wide range of melting temperatures, enabling situations such as the coexistence of melting and crystallization. This feature will be exploited for a self seeding technique.The properties of the resulting well ordered highly perfect single crystals will yield improved electrical, mechanical and optoelectronic properties of these polymers. These perfect electron pathways can be used in many optoelectronic devices with improved performance. However, we shall apply in fabrication of organic thin film field effect transistors (OFETs) with a high field effect mobility (μ) between the source and the drain improving it’s performance immensely.
