Engineering Strategies for 2D Layered Tin Halide Perovskite Field‐Effect Transistors
Advanced Functional Materials, EarlyView.2D halide perovskites are promising candidates for field‐effect transistor (FET) applications due to their high stability and suppressed ion migration in the presence of bulky organic spacers. This review systematically summarizes the optimization engineering strategies of 2D perovskite FETs and future challenges, which provide guidance for developing ...
