(PhysOrg.com) -- Organic semiconductors are promising building blocks for many devices, from LEDs to transistors, offering potential advantages such as cost-effectiveness, flexibility, and high performance. Currently, most research in organic semiconductors has focused on p-channel semiconductors, which transport positively charged holes, rather than n-channel semiconductors, which transport negatively charged electrons. The choice of semiconductor depends on the application, and many applications require a combination of both types. However, the few n-channel semiconductors that exist today have performance that lags considerably behind their p-channel counterparts.
