Aiming to overcome the limitations of Si-based logic circuits by combining optoelectronic technology with FETs, switching of FET characteristics was investigated by utilizing photoisomerization of photochromic molecules. A trans-azobenzene solution was poured into a MoS2-FET with a microfluidic channel attached, and cis-isomerization was induced by UV light irradiation. A shift of the Id-Vg curve between the two states was observed. This method is promising for controlling the characteristics of photosensitive FETs. Experiments using other photochromic molecules will also be presented on the day.
