Monthly new tech capsule: organic semiconductor material "Pentacene"

The present popularly used semiconductor devices/ICs are rigid and hardly flexible. What if you want to put a flexible RFID circuit on a clothing or some packaging material of a food or such perishable/consummable material. Use of silicon or any such in-organic semiconductor material is expensive. Electronic material researchers are using organic semiconductor materials for such applications which can be printed to form integrated circuits on surfaces of flexible sheet like material using simple technologies such as inkjet printing. One of the most popular organic semiconductor material now the industry is using is Pentacene. Pentacene is a aromatic hydrocarbon made out of benzene rings. Pentacene is used to fabricate organic LED-based LCD displays and also for designing solar PV cells. The technical issues faced with organic semiconductor material such as Pentacene is they have very weak electron mobility and the metal semiconductor junctions are inconsistent in performance causing reliability issues. These are causing the challenges for researchers to use Pentacene as full-fledged commercial production of organic semiconductor devices. Here we provide some of the best sources to learn further on Pentacene: The basic properties of Pentacene is well explained with good number of pictures at: http://www.chm.bris.ac.uk/motm/pentacene/pentacene.htm Researchers at B...
