AsBr3
semiconductor· AsBr3
AsBr₃ is an arsenic tribromide compound belonging to the family of layered semiconductor materials with a layered crystal structure similar to other group V-VI pnictogens. This is primarily a research and development material rather than an established commercial compound, explored for potential applications in optoelectronics and low-dimensional semiconductor devices where its layered nature enables exfoliation into thin films. Engineers investigating AsBr₃ are typically interested in it as a candidate for next-generation semiconductors with tunable bandgaps and novel electronic properties that differ from bulk three-dimensional semiconductors.
