Confirmation of direct photogeneration of intrinsic delocalized free carriers in small-molecule organic semiconductors has been a long-sought but unsolved issue, which is of fundamental significance to its application in photo-electric devices. Although the excitonic description of photoexcitation in these materials has been widely accepted, this concept is(More)
Single-crystal-like organic heterojuntions are fabricated with disk-like molecules and different rodlike molecules. Hole transparent and blocking transport are demonstrated with photoemission spectroscopy and field-effect transistors. These results demonstrate a route to utilize adjustable interfacial electronic structure and control transport behavior in(More)
