Abstract

Novel cationic quaternary chalcohalide nanobelts were found in Hg₄In₂Q₃Cl₈ (Q = S, Se, Te), obtained by solid-state reaction. Due to the effects of dimensional reduction, both theoretical and experimental results demonstrate that their bandgaps are remarkably increased compared to those of the zinc-blende structure HgQ (Q = S, Se, Te).
