Halide perovskites have emerged as a promising family of candidates with remarkable physical features combined with facile processing, holding great potential in various electronic applications beyond the widely reported photovoltaics and optoelectronics. Compared with the polycrystalline counterparts, single-crystal perovskites with excellent carrier dynamics and outstanding stabilities demonstrate more promising electronic device potentials. Herein, we present a comprehensive review on the fascinating field of single-crystal perovskite electronics with a particular focus on transistors and memory devices. To begin with, the fundamental features of this class of crystals that allow for the electronics are highlighted. Thereafter, recent achievements on the single-crystal perovskite transistors, as well as the applications of perovskite crystals in memories and artificial synapses, are reviewed in detail. The main challenges of single-crystal perovskite electronics are then discussed, followed by the brief perspectives for further developing solution-processed perovskite crystal electronics as a competitive and replacing technology.
