Two dimensional band structure mapping of organic single crystals using the new generation electron energy analyzer ARTOF

► A novel type of photoemission detector is introduced: the Angle Resolved Time Of Flight electron energy analyzer (ARTOF). ► It enables electronic band structure determination under measurement conditions that are ideal for radiation-sensitive samples. ► The band structures of rubrene single crystal is confirmed. ► The absence of HOMO-band dispersion for tetracene single crystals is revealed.
