Spin Selectivity in Chiral Hybrid Cobalt Halide Films with Ultrasmooth Surface

“…[38,39] Up to now, pursuing ultralow roughness to improve device performance has an important technical task for classical spintronic materials (Co, Y 3 Fe 5 O 12 ). [40,41] Furthermore, the ultrasmooth interface is promising for constructing original devices and exploring emergent physics, as the boom of Introducing chirality into low-dimensional hybrid organic-inorganic halides (HOIHs) creates brand-new opportunities for HOIHs in spintronics and spin-related optoelectronics owing to chirality-induced spin selectivity (CISS). However, preparing smooth films of low-dimensional HOIHs with small roughness is still a great challenge due to the hybrid and complex crystal structure, which severely inhibits their applications in spintronic devices.…”

“…[ 38,39 ] Up to now, pursuing ultralow roughness to improve device performance has an important technical task for classical spintronic materials (Co, Y 3 Fe 5 O 12 ). [ 40,41 ] Furthermore, the ultrasmooth interface is promising for constructing original devices and exploring emergent physics, as the boom of van der Waals spintronics in recent years. [ 42,43 ] Even for other optoelectronic applications (e.g., photovoltaic solar cells, [ 44,45 ] lasers, [ 46 ] PeLED, [ 47 ] field‐effect transistors [ 48 ] ), numerous efforts have been paid to improving film quality to avoid the adverse impact from defects.…”
