Molecular doping of high mobility small molecule semiconductors
IAPP’s pioneering molecular doping technology is a key enabler for organic light-emitting diodes and solar cells to reach industrial maturity. This thesis project aims at studying the molecular doping of high mobility organic small-molecule semiconductors for exploratory applications beyond established organic electronic technology [1,2]. The study will make use a set of comprehensive experimental techniques including electrical and optical spectroscopy to gain insights into charge transport of such doped systems.
Triclinic rubrene crystalline thin-films and their transport properties with doping [1].
