semiconductor· In2Bi3Se7I
In2Bi3Se7I is a quaternary chalcohalide semiconductor compound combining indium, bismuth, selenium, and iodine in a layered crystal structure. This is a research-stage material studied for its potential as a narrow-bandgap semiconductor with interesting optoelectronic and thermoelectric properties, part of the broader family of bismuth chalcohalides being investigated as alternatives to lead-based compounds in photovoltaics and IR detection. The material represents exploratory work in non-toxic, earth-abundant semiconductors that could enable new applications in mid-infrared sensing and solid-state energy conversion if synthetic and processing challenges can be overcome.
