The invention discloses a double-top-electrode 4H-SiC position detector and a preparation method and application thereof. The double-top-electrode 4H-SiC position detector comprises a 4H-SiC substrate, a first electrode, a second electrode and a third electrode, the first and second top electrodes are arranged on the silicon surface of the substrate and are separated from each other; the bottom electrode is arranged on the carbon surface of the substrate. According to the detector, high-precision linear detection of the incident light position is realized in a single 4H-SiC material system by using a discrete double-top-electrode structure, and the problem that a traditional single-electrode structure cannot perform position sensing is solved; meanwhile, the problem of a heterogeneous material interface is fundamentally avoided through the full 4H-SiC-based monolithic structure, so that the long-term stability and reliability in extreme environments such as high temperature and intense radiation are remarkably improved by virtue of the excellent wide-band gap characteristic of the 4H-SiC material and the intrinsic stability of the structure while the high position detection precision is maintained; the problem that an existing position detector with a complex structure is insufficient in environment tolerance is solved.
