Tribotronic triggers and sequential logic circuits

引用

Nano Research 2017年第10期10卷 3534-3542页

作者： Li Min Zhang Zhi Wei Yang Yao Kun Pang Tao Zhou Chi Zhang Zhong Lin Wang Beijing Institute of Nanoenergy and Nanosystems Chinese Academy of Sciences National Center for Nanoscience and Technology Beijing 100083 China School of Material Science and Engineering Georgia Institute of Technology Atlanta GA 30332-0245 USA

In this paper, a floating-gate tribotronic transistor （FGTT） based on a mobile triboelectric layer and a traditional silicon-based field-effect transistor （FET） is proposed. In the FGTT, the triboelectric charges in the layer created by contact electrification can be used to modulate charge carrier transport in the transistor. Based on the FGTTs and FETs, a tribotronic negated AND （NAND） gate that achieves mechanical-electrical coupled inputs, logic operations, and electrical level outputs is fabricated. By further integrating tribotronic NAND gates with traditional digital circuits, several basic units such as the tribotronic S-R trigger, D trigger, and T trigger have been demonstrated. Additionally, tribotronic sequential logic circuits such as registers and counters have also been integrated to enable external contact triggered storage and computation. In contrast to the conventional sequential logic units controlled by electrical signals, contact-triggered tribotronic sequential logic circuits are able to realize direct interaction and integration with the external environment. This development can lead to their potential application in micro/nano-sensors, electromechanical storage, interactive control, and intelligent instrumentation.
