| 1 | Recent advances in controlling the crystallization of two-dimensional perovskites for optoelectronic device显示文摘Though three-dimensional (3D) organic inorganic halide perovskites (OIHP) is very promising for low cost and distributed PV generation,the stability issue of 3D OIHP is still a problem for its commer-cialization.Two-dimensional (2D) perovskites,protected by periodic organic ligands,is promising due to its excellent optoelectronic property and superior stability.However,2D perovskitc is anisotropic in its crystal structure and optoelectronic properties,and the resulted film is often a mixture of different phase.So,methods to manipulate 2D perovskitc crystal orientation and its phase separation are vital.In this review,the major advances on the composition engineering,crystal orientation,phase separa-tion,and inlerfaeial capping are summarized.Besides,efforts on understanding the formation process of 2D perovskitc crystal arc also discussed,which is important for making full use of 2D perovskitc in functional optoelectronic devices. | Shi-Qiang Luo Ji-Fei Wang Bin Yang Yong-Bo Yuan | 2019 | Frontiers of physics2019，14，5： | 6 |
| 2 | Two-dimensional materials for light emitting applications:Achievement,challenge and future perspectives显示文摘The two-dimensional(2D)materials have been widely developed recently in material characteristics with advanced optical and electrical properties,and they have been extensively studied as candidates for the next generation of optoelectronic devices.This review will mainly focus on the preparation methods and the light emitting applications of 2D transition metal dichalcogenides(TMDs),2D black phosphorene(BP)and 2D perovskites.The review will first introduce the preparation methods for TMDs and BP.Due to the variations of band structure,exciton binding energies and light-matter interaction in TMDs and BP,the different light emitting devices(LEDs)designs based on TMDs and BP will be discussed and summarized.Then the review will turn the focus to 2D perovskites,starting with a description of the preparation methods for the different structural perovskites.In order to review and summarize the achievements of 2D perovskites-based LEDs,the high efficiency perovskites LEDs are discussed.Finally,the review will present challenges,opportunities,and outlook for the future development of 2D materials-based light emitting applications. | Yi Zhu Xueqian Sun Yilin Tang Lan Fu Yuerui Lu | 2021 | Nano Research2021，14，6： | 2 |
| 3 | 钙钛矿场效应晶体管中的离子迁移(特邀)显示文摘场效应晶体管是一种通过电压控制电路的电子开关,是现代电子技术的关键元件。随着新型半导体材料的发展,场效应晶体管沟道材料的选择更加多样化。近年来,钙钛矿材料作为一种新型的有机无机杂化半导体材料在光伏和发光领域发展迅速,但由于其本身具有离子迁移的特性,限制了其在场效应晶体管领域的发展。钙钛矿材料中的离子迁移能够引起栅极电场的部分屏蔽,影响栅极的调制作用,降低场效应晶体管的迁移率。本文系统阐释了离子迁移现象的产生机理,总结了抑制离子迁移的方法,最后展望了钙钛矿晶体管的应用前景。 | 董雪 程鹏 郭佩瑶 刘国桦 李逸群 吴忠彬 陈永华 黄维 | 2021 | 光子学报2021，50，10： | 1 |
