WebFeb 23, 2024 · The crystal structure of FeO 2 is composed of Fe 2 + and O 2 2 − dimers, where the Fe ions are surrounded by the octahedral O atoms. We found that FeO 2 shows a metal-insulator transition (MIT) under high pressure. The MIT is not a Mott type but a band insulator type which is driven by the O 2 dimer bond length change. http://www.xiamenjiyang.com/products_show.asp?id=2248
