Researchers find innovative way to store and process information by maintaining valley polarization at room temperature

"single crystals chiral lead halide perovskites (R/S-NEAPbI3). Chirality controlling valley polarization... 500 nm flakes layered onto molybdenum disulfide (MoS2) TMD monolayer create heterostructure... TMDs have 2 valleys with same energy... electron can be in 1 valley or other so information stored same way as 1s and 0s... heterostructure lower emission than bare TMD... few trillionths of second charge transfers... selectively populate valleys and use their occupation in  efficient computers, quantum computing"
