Tm1 Bi2 I1 O4
semiconductor· Tm1 Bi2 I1 O4
Tm₁Bi₂I₁O₄ is an experimental mixed-metal oxide-iodide semiconductor combining thulium, bismuth, and iodine in a layered crystal structure. This material belongs to the rare-earth bismuth halide family, which is actively researched for optoelectronic and photovoltaic applications where tunable bandgaps and layered transport properties offer advantages over conventional semiconductors. The incorporation of thulium (a lanthanide) and bismuth—both known for strong spin-orbit coupling—makes this compound of interest for next-generation photon detection, X-ray sensing, and potentially topological electronic devices, though it remains largely in the research phase without established large-scale industrial production.
