With the support of the Macromolecular, Supramolecular, and Nanochemistry (MSN) program in the Division of Chemistry, Professor Jin Zhang of University of California-Santa Cruz and Professor Yuan Ping of University of Wisconsin-Madison are using advanced computational and laser techniques to study the behavior of electron spin in two-dimensional (2D) metal halide double perovskites. Electron spin is a fundamental quantum mechanical property useful for applications such as information encoding and storage. Many emerging applications require long spin state lifetime and precise control. However, spin lifetime is usually short, a fraction of a second, and challenging to manipulate and use in devices. The research will create new 2D perovskites with long spin lifetimes and use ultrafast lasers to probe and control spin. Their discoveries could impact technologies from nanoelectronics to quantum information technologies including quantum computing and communication. The project will also provide training opportunities for future scientists, and through their “open lab” with a theme on “Spectroscopy and Sunny Santa Cruz” (SSSC)”, it will introduce research to local high school students and communities to enhance public awareness about science.
