Electron transport properties of a narrow-bandgap semiconductor Bi${}_2$O${}_2$Te nanosheet

Xiaobo Li, Haitian Su, H. Q. Xu

A thin, narrow-bandgap semiconductor Bi${}_2$O${}_2$Te nanosheet is obtained via mechanical exfoliation and a Hall-bar device is fabricated from it on a heavily doped Si/SiO${}_2$ substr…
