DOI: 10.1002/adma.202208343
Abstract: Dual topological insulators, simultaneously protected by time‐reversal symmetry and crystalline symmetry, open great opportunities to explore different symmetry‐protected metallic surface states. However, the conventional dual topological states located on different facets hinder integration into planar… read more here.

DOI: 10.1039/d2nr06919a
Abstract: Low-temperature solution-made chiral lead halide perovskites (LHPs) have spontaneous Bychkov-Rashba spin orbit coupling (SOC) and chiral-induced spin selectivity (CISS) qualities. Their coexistence may give rise to considerable spin and charge conversion capabilities for spin-orbitronic applications.… read more here.
