Stanford University and Samsung researchers have patented a microfluidic-based platform that can rapidly fabricate and characterize Organic Thin Film Transistor (OTFT) arrays composed of solution-processable organic semiconducting polymers.
Although organic thin film transistors (OTFTs) made from organic semiconductors are valued for their transparency, flexibility and low cost attributes, their sluggish response time due to slow carrier mobility limits their applications.
Stanford researchers have developed a versatile molecular engineering approach, via random copolymerization, to gain good processability while maintaining high charge transport and photovoltaic performance for conjugated copolymers.
Researchers in Prof. Zhenan Bao's laboratory have invented a novel semiconducting material containing siloxane-containing side chains. This material demonstrates high charge carrier mobility, as well as air and operational stability in field effect transistor devices.
