| 摘要: |
| 可室温运转的高灵敏度太赫兹探测器是该领域的难点。热电原理的太赫兹探测器为解决室温下的宽频段、高灵敏探测提供可能。通过利用石墨烯和钙钛矿等新型微纳材料的高载流子迁移率和优异的热电性能,制备出高性能室温运转的太赫兹光电探测器,探测的光电响应度最高可达到271 mA/W,响应时间小于20 ms。研究表明,石墨烯和钙钛矿等光热电探测器有望成为太赫兹频段新一代高性能探测器。 |

| Abstract: |
| The realization of high sensitivity terahertz detector which can be operated at room temperature poses difficulty in this field. The terahertz detector based on the principle of thermoelectricity provides the posibility for wide detection frequency range and high sensitivity detection at room temperature. By utilizing the high carrier mobility and excellent thermoelectric properties of new micro-nano materials such as graphene and perovskite, the high-performance terahertz photodetectors operating at room temperature were prepared, the detection of the photoelectric response can be up to 271 mA/W, and the response time is less than 20 ms. Results show that photothermoelectric detectors prepared by graphene and perovskite are expected to be a new generation of high performance detectors in terahertz frequency band. |
