In this work, graphene-methylammonium lead iodide (MAPbI<sub>3</sub>) perovskite hybrid phototransistors fabricated by sequential vapor deposition are demonstrated. Ultrahigh responsivity of 1.73 × 10<sup>7</sup> A W<sup>-1</sup> and detectivity of 2 × 10<sup>15</sup> Jones are achieved, with extremely high effective quantum efficiencies of about 10<sup>8</sup>% in the visible range (450-700 nm). This excellent performance is attributed to the ultra-flat perovskite films grown by vapor depositio ...[more]
