Giant current amplification induced by ion migration in perovskite single crystal photodetectors
Abstract
A giant current amplification was observed in the lateral organic–inorganic perovskite single crystal photodetectors. It was proposed that photoexcitation and electrical field induced migration and accumulation of ions at respective contacts. The interfacial charging due to ion accumulation offers an effective mechanism to trigger counter charge injection, consequently amplifying the total electrical current.
