Publication number: 20240008294Abstract: The present invention relates to an organic thin film transistor (OTFT) comprising an organic semiconductor layer (2) arranged between a source terminal (3) and a drain terminal (4). The OTFT further includes a front gate (5) electrode arranged on one side of the organic semiconductor layer and a back gate electrode (6) arranged on the opposite side of the organic semiconductor layer. The front and back gate electrodes are arranged to control the current flow in the organic semiconductor layer upon application of a voltage and the back gate electrode is electrically connected to one of: the front gate electrode and the source terminal. OTFT's according to the present invention, with a connection between the back gate and the source or front gate, exhibit improved turn on voltage stability, lower power consumption and improved bias stress stability compared to single gate and back gate isolated OTFTs.Type: ApplicationFiled: November 16, 2021Publication date: January 4, 2024Applicant: SMARTKEM LIMITEDInventors: Beverley BROWN, Chia-Hung TSAI, Dan SHARKEY, Alejandro CARRERAS, Simon OGIER
