Realization of Asymmetric Spintronic Terahertz Radiation in Two-Dimensional Hybrid Metal Halides

ORaCEL researchers have demonstrated the emission of terahertz radiation in a spintronic device. By coupling a two-dimensional hybrid metal halide with a ferromagnetic metal, asymmetric spintronic-THz radiation is produced by the ultrafast spin current under femtosecond laser excitation. The device is thinner, lighter, and less expensive to produce compared to conventional terahertz generators. This work that is co-authored by Prof. Dali Sun (NCSU) and  Wei You (UNC-Chapel Hill) appears in a recent issue of Nature Communications.

The detailed story appears in the NCSU News outlet.
