To date, surface nanostructures on organic-inorganic single-crystal perovskites have been achieved mainly through destructive methods such as electron-beam lithography and focused ion beam milling. Here, we present a solution-based epitaxial growth method for creating nanopatterns on the surface of perovskite monocrystalline thin films. We show that high-quality monocrystalline arbitrary nanopatterns can form in solution with a low-cost simple setup. We also demonstrate controllable photoluminescence from nanopatterned perovskite surfaces by adjusting the nanopattern parameters. A seven-fold enhancement in photoluminescence intensity and a three-time reduction of the surface radiative recombination lifetime are observed at room temperature for nanopatterned MAPbBr3 monocrystalline thin films. Our findings are promising for the cost-effective fabrication of monocrystalline perovskite on-chip electronic and photonic circuits down to the nanometer scale with finely tunable optoelectronic properties. ## Links - DOI: https://doi.org/10.1021/acsnano.9b08553 - OpenAlex: https://openalex.org/W3080930301 - PDF: https://qmro.qmul.ac.uk/xmlui/bitstream/123456789/66750/2/Su%20Solution-Processed%20Epitaxial%202020%20Accepted.pdf - JSON API: https://science-database.com/api/v1/technology/semiconductor --- Generated by science-database.com — The Knowledge Interface Paper ID: oa-W3080930301 | Hub: semiconductor
