Microfluidic Arrays for Rapid Characterization of Organic Thin Film Transistor Performance
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. Microfluidics offers numerous advantages for this high-throughput screening of OTFTs including the ability to:
1) rapidly handle and interface multiple solutions;
2) pattern solutes on substrates with micrometer-scale precision; and
3) reduce the scale of experimentation.
This method has been successfully tested to screen the performance of OTFT devices fabricated from PQTBTz-C12, a solution processable organic semi-conducting polymer, to extract empirical processing-property relationships and identify the optimal combination of solvent composition and substrate annealing temperature.
Stage of Development:
Proof-of-concept – Successfully applied platform to screen performance of OTFT devices fabricated from PQTBTz-C12 to extract empirical processing-property relationships and identify the optimal combination of solvent composition and substrate annealing temperature.
