采用自组装重结晶法首次合成了二维苯乙胺（PEA，C8 H9 NH3）Bi-Ag双钙钛矿（PEA）4 BiAgX 8（X = Br，I）微晶片.微片的吸收光谱表现出直接带隙和不同的卤化物组合物显示出不同的形态和带隙可调性。基于单个（PEA）4 BiAgBr 8微片晶的场效应晶体管显示p型半导体行为。
Two-dimensional phenylethylammonium (PEA, C8H9NH3) Bi–Ag double perovskite (PEA)4BiAgX8 (X = Br, I) microplatelets are synthesized for the first time via a facile self-assembly recrystallization method. Absorption spectra of microplatelets exhibit direct bandgaps and different halide compositions show distinct morphologies and bandgap tunability. Field-effect transistors based on a single (PEA)4BiAgBr8 microplatelet display a p-type semiconducting behavior.
