Title: 2D perovskites: Tuning Orbit-Orbit Interaction To Advance Circular Polarization-Induced Spin Effects, Optic, and Electronic Properties By Controlling Thermodynamics in Forming Spin-Cast Films
Date & Time: 8th July (Fri.) 13:30～
Venue: Noyori Lecture Room
Host: Kunio Awaga awaga.kunio.h8<at>f.mail.nagoya-u.ac.jp (<at>→＠）
2D perovskites are known as solution-processing multifunctional 2D materials formed with inorganic-semiconducting layers carrying high-dielectric constant separated by insulating organic molecules with low-dielectric constant. The alternatively arranged high-dielectric inorganic layers and low-dielectric insulating organic molecules lead to ordered 2D multiple-quantum-well electronic structures by confining charge carriers within high-dielectric inorganic-semiconducting layers.
Interestingly, the 2D multiple-quantum-well structures are simultaneously formed with spin-orbital coupling ordering, cooperative electron-phonon coupling, and Rashba band structures. Consequently, 2D perovskites can demonstrate circular polarization-induced spin phenomena, superior optoelectronic properties through orbit-orbit interaction, slow cooling of hot electrons towards ballistic transport, and quantum oscillation of conduction electrons at room temperature.
Therefore, 2D perovskites with solution-processing capabilities present a unique platform to explore new obitronics, spintronics, and photo-physics phenomena. This presentation will discuss tuning the multifunctional properties through orbit-orbit interaction in 2D perovskites by controlling the thermodynamics in forming spin-cast films.
