Diamond solution gate field effect transistor system

Abstract

The invention discloses a diamond solution gate field effect transistor system and a detection method. The system comprises a diamond solution gate field effect transistor and a reference electrode which are independently arranged each other and placed into seawater at intervals, the diamond solution gate field effect transistor and the reference electrode form a capacitor, the outer end of the reference electrode is connected with a voltage signal source, and the diamond solution gate field effect transistor is connected with a voltage reader. The system is used for detection and communication by the aid of electric signals, propagation speed is high, interference of objects in water to the system is less, long-distance propagation can be implemented, so that limit of detection and communication distance is reduced, long-distance detection and communication can be achieved, detection sensitivity is improved by a transmission mode of the electric signals, millivolt-scale change can bedetected, and delaying time of the system is shortened and within a few microseconds.

Description

technical field [0001] The invention belongs to the technical field of semiconductor devices, and in particular relates to a diamond solution gate field effect transistor system. Background technique [0002] Because sound waves can travel long distances in water media, they have always been regarded as an effective underwater information carrier. Underwater acoustic detection, communication, positioning and navigation technologies have also been key research objects in the marine field. However, on the one hand, due to the complexity of the water medium, the sound wave is seriously interfered by the reflected sound waves of the water surface, the bottom of the water, objects in the water and the noise in the water during the application process; All these limit the development of underwater acoustic technology and affect the effectiveness and reliability of its detection, communication, positioning and navigation. [0003] In recent years, as quiet targets such as quiet su...
