论文摘要
金属卤化物钙钛矿是显示光伏和光发射的独特特征的材料。这些材料与发光二极管和发光晶体管中的电致发光一起显示了放大的自发发射和刺激的发射。结合刺激的发射和电致发光的重要成就可能是制造电动金属卤化物钙钛矿激光器。在这项工作中，提出了金属卤化物钙钛矿发光场效应晶体管与光子微腔的集成。这可能导致电动激光器的工程。已经设计了微腔是为了在750 nm处具有空腔模式，这是最近报道的基于MAPBI3的电致发光设备的电致发光光谱的峰值波长。考虑到所有涉及的所有材料的依赖性折射率，已经通过转移矩阵方法模拟光子微腔的光学特性。该栅极的材料是二锡氧化物，虽然已经考虑了微博结构的不同材料（无机或有机）。
Metal halide perovskites are materials that show unique characteristics for photovoltaics and light emission. Amplified spontaneous emission and stimulated emission has been shown with these materials, together with electroluminescence in light-emitting diodes and light-emitting transistors. An important achievement that combine stimulated emission and electroluminescence could be the fabrication of electrically driven metal halide perovskite lasers. In this work, the integration of metal halide perovskite light-emitting field-effect transistors with photonic microcavities is proposed. This can lead to the engineering of electrically driven lasers. The microcavities have been designed in order to have the cavity mode at 750 nm, which is the peak wavelength of the electroluminescent spectrum of recently reported MaPbI3-based electroluminescent devices. The optical properties of the photonic microcavities have been simulated by means of the transfer matrix method, considering the wavelength dependent refractive indexes of all the materials involved. The material for the gate is indium tin oxide, while different materials, either inorganic or organic, have been considered for the microcavity architectures.
