Chalcogen alloying for band structure modulation of antimony chalcogen iodide alloy: 1D van der Waals materials SbSI–SbSeI system

Alloys of SbSI and SbSeI, 1D van der Waals materials, were synthesized through chalcogen atom substitution. The band structure and photocurrent were modulated based on the composition of the synthesized alloy.
