Organic tribotronics transistor and contact electrification gate-controlled light-emitting device

Abstract

The invention provides an organic tribotronics transistor. The organic tribotronics transistor comprises a substrate, an organic thin-film transistor formed above the substrate and a frictional nano generator formed below the substrate. The frictional nano generator comprises a static friction portion formed at the lower surface of the substrate and a movable friction portion arranged opposite to the static friction portion, wherein one of the static friction portion and the movable friction portion is electrically connected with a source electrode of the organic thin-film transistor, and the other is electrically connected with a grid electrode of the organic thin-film transistor. The organic tribotronics transistor utilizes electrostatic potential generated by a frictional generator to act as a gate electrode gate signal so as to realize regulation and control for transport characteristics of carriers in a semiconductor, thereby having good regulation and control characteristics, and realizing a brand new mode of regulating and controlling light emission of a device through mechanical input. Based on the organic tribotronics transistor, the invention further provides a contact electrification gate-controlled light-emitting device.
