Congratulations to Dr. Seohee Kim, whose publication titled “Polarization effects from the ambient and the gate dielectric on charge transport in polymer field-effect transistors” was selected by Applied Physics Letters (APL) as the Editor’s Choice. Using a FET device featuring high mobility polymer PDPP2T-TT-OD and a bilayer gate dielectric, Dr. Kim showed polarization induced trapping enhancement through a series of experiments that modified the conditions of the surface dielectric and introduced polar analytes to the atmosphere.
