Previously we reported a compact one-transistor (1T) 180 nm bulk CMOS cryo-memory with a high 10^7 I_1/I_0 memory window and long 800 s retention time based on impact-ionization-induced charging of the transistor body. Here, we present the endurance and

The capacity to manipulate magnetization in 2D dilute magnetic semiconductors (2D-DMSs) using light, specifically in magnetically doped transition metal dichalcogenide (TMD) monolayers (M-doped TX2, where M = V, Fe, and Cr; T = W, Mo; X = S, Se, and Te)
