Photoswitchable OFETs controlled by optical bistability in the dielectric layer

Interest in electronic properties of organic materials has been stimulated by emerging prospects of their application in electronics and photonics [1–4]. Among potential applications, one may envisage use of organic materials as active elements of molecular switches. According to a general definition, a switch is a mechanical, electrical, electronic, or optical device for opening or closing a circuit, or for diverting energy or charge from one part of a circuit to another. In this context, photochromic materials have been extensively studied.
