| titleOfInvention | Construction Method of High Sensitivity Nitrogen Dioxide Gas Sensor Based on Van der Waals Junction Thin Film |
| abstract | The invention relates to a construction method of a high-sensitivity nitrogen dioxide gas sensor based on a van der Waals junction film, which is characterized in that a high-quality semiconductor quantum sensor is prepared by an optimized "one-step" chemical synthesis without adding any surfactant Dots, uniformly modify semiconductor quantum dots on graphene prepared by chemical vapor deposition by spin coating, control the annealing temperature and time of the device, optimize and improve the van der Waals contact between semiconductor quantum dots and graphene, and prepare semiconductor quantum dots Dot/graphene van der Waals junction NO gas sensor. When the NO2 gas concentration is 25ppm, the response sensitivity of the device at room temperature is 580%, the response time is about 10s, and the recovery time is about 150s. In addition, the device also exhibited good response cycle stability and selectivity. The construction method of the flexible device is simple, controllable and highly repeatable, so it has obvious application value. |
