Replication Data for: Tunable room-temperature spin-selective optical Stark effect in solution-processed layered halide perovskites
May 31, 2019
Giovanni, David; Chong, Wee Kiang; Dewi, Herlina Arianita; Thirumal, Krishnamoorthy; Neogi, Ishita; Ramesh, Ramamoorthy; Mhaisalkar, Subodh; Mathews, Nripan; Sum, Tze Chien, 2019, "Replication Data for: Tunable room-temperature spin-selective optical Stark effect in solution-processed layered halide perovskites", https://doi.org/10.21979/N9/BWMJDV, DR-NTU (Data), V2
Ultrafast spin manipulation for opto–spin logic applications requires material systems that have strong spinselective light-matter interaction. Conventional inorganic semiconductor nanostructures [for example, epitaxial II-VI quantum dots and III-V multiple quantum wells (MQWs)]...
