Indigo -- A biodegradable, low-cost organic semiconductor for device applications

In recent years, the use of organic semiconductors for device applications has attracted considerable attention. In this paper, recent results on indigo-based devices will be reviewed. Indigo is a biodegradable and a low-cost semiconductor with band gap of 1.7 eV and its use in field effect transistors and circuits has been recently reported [1]. In our work, we have recently developed indigo-based write-once-read-many-times (WORM) memory device [2]. Details of the results and their interpretation in terms of interfacial dipoles will be presented. \\[4pt] [1] M. Irimia-Vladu et al, Adv. Mater. 24, 375 (2012).\\[0pt] [2] Z. Wang, K. Sierros, D.
