Abstract

Doping is an important technique for semiconductor materials and devices, yet effective and controllable doping of organic-inorganic halide perovskites is still a challenge. Here, we demonstrate a facile way to dope 2D Sn-based perovskite (PEA)2SnI4 by incorporating SnI4 in the precursor solutions. It is observed that Sn4+ produces p-doping effect on the perovskite, which increases the electrical conductivity by 105 times. This doping technique allows us to improve the mobility of (PEA)2SnI4 field-effect transistors from 0.25 to 0.68 cm2 V−1 s−1. This solution-processed doping technique is promising for flexible and high-performance devices.

用于高性能场效应晶体管和热电器件的锡基二维钙钛矿半导体掺杂

掺杂是半导体材料和器件的重要技术，但有效、可控地掺杂有机-无机卤化物钙钛矿仍然是一个挑战。在这里，我们展示了一种简单的方法，通过将SnI4掺入前驱体溶液中来掺杂2D sn基钙钛矿(PEA)2SnI4。观察到Sn4+在钙钛矿上产生p掺杂效应，使钙钛矿的电导率提高了105倍。这种掺杂技术使我们能够将(PEA)2SnI4场效应晶体管的迁移率从0.25提高到0.68 cm2 V−1 s−1。这种溶液处理掺杂技术有望用于柔性和高性能器件。

期刊介绍： Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results. We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
