The invention discloses a preparation method and application of a large-area honeycomb-like bismuth sulfide flexible film, and belongs to the technical field of semiconductor detection materials and preparation thereof. A large-area honeycomb-like Bi2S3 flexible thin film is prepared by a low-pressure chemical vapor deposition method, and the flexible thin film is formed by arranging stable triangular unit structures, so that the flexible thin film is of an interconnected network structure. Wherein each triangular unit structure is formed by interweaving one-dimensional nanobelts which are regularly arranged. A flexible wide-spectrum photoelectric detector with a simple process is designed based on a large-area honeycomb-like Bi2S3 flexible thin film. The prepared detector can detect ultraviolet light, visible light and infrared light, and has high responsivity, quick response characteristic and excellent stability under a bending condition. More importantly, the device still shows excellent cycling stability and air stability after being continuously bent for a circle in the air without any packaging.

This application discloses an isolation circuit based on a load switch, belonging to the field of electrical isolation circuit technology. The isolation circuit includes: directly connecting the power input terminal and the enable terminal of the load switch module through a first resistor. The level of the enable terminal changes synchronously with the level of the power input terminal. This eliminates the need for an external control source to enable or disable the power supply path between the power input and output terminals of the load switch module, thus achieving synchronous triggering of power supply on / off and power level changes. This eliminates the timing obstacles of residual current discharge and rapid voltage drop after power failure in the load circuit, solving the problem of traditional technologies where the inability to synchronously trigger power supply on / off leads to the downstream circuit voltage not quickly returning to zero, thus causing reset abnormalities. This effectively ensures the fast response characteristics of the isolation circuit and can meet the practical application requirements of various electronic circuits for fast isolation circuit response.
