Low-Temperature Growth of Two-Dimensional Layered Chalcogenide Crystals on Liquid.

摘要: The growth of high-quality two-dimensional (2D) layered chalcogenide crystals is highly important for practical applications in future electronics, optoelectronics, and photonics. Current route the synthesis 2D by vapor deposition method mainly involves an energy intensive high-temperature process on solid substrates, often suffering from inhomogeneous nucleation density grain size distribution. Here, we first demonstrate a facile vapor-phase large-area liquid metal surface with relatively low at temperature as ∼100 °C. Uniform large-domain-sized GaSe GaxIn1–xSe were grown even supported polyimide film. As-grown have been fabricated to flexible photodetectors, showing high photoresponse excellent flexibility. Our strategy energy-sustainable low-temperature may open ro...
