Self-driven all-inorganic perovskite microplatelet vertical Schottky junction photodetectors with a tunable spectral response
Wavelength-selective perovskite photodetectors (PDs) have many applications in optoelectronic fields, such as machine vision, imaging and full-color displays. However, the instability of organo-inorganic hybrid perovskite materials severely limits the commercialization of perovskite-based PDs. In th...

MP Schottky PDs exhibit a rapid response speed (75 μs) and a very low dark current (2 pA) at zero bias. Meanwhile, the device shows a high on/off ratio (>10

These results provide a simple avenue to realize self-driven and spectrally tunable all-inorganic perovskite Schottky PDs with good stability.
