FOUR-TERMINAL GATE-CONTROLLED THIN-FILM ORGANIC THYRISTOR

摘要

Technologies are generally described for a four-terminal, gate-controlled, thin-film thyristor device. The thyristor device may essentially be an n-type thin-film transistor (TFT) with an additional emitter terminal. The thyristor device may exhibit an S-shaped negative differential 5 resistance (NDR) characteristic resulting from conductance modulation. The conductance modulation may be caused by formation of a secondary channel for current flow due to an inherent structure of the device. The secondary channel may be formed in a semiconductor area within the device, the semiconductor area including a hole transporting organic semiconductor layer (HTL) and an electron transporting organic semiconductor layer (ETL). A gate terminal of 10 the thyristor device may further allow onset of NDR characteristics to be controlled and may allow the device to be switched off.
