Title: PHASE SEPARATION FOR ENHANCED CARRIER MOBILITY IN OTFT DEVICES
Abstract:
The present invention relates to effecting vertical phase separation in a blend comprising an organic semiconductor and a semiconducting fluorous polymer having a low surface energy and thereby simultaneously depositing organic semiconductor material a top coat layer polymer having favourable hydrophobicity, which allows to produce organic thin film transistors (OTFTs) with improved carrier mobility in a simple manner.
