WebApr 9, 2024 · Ferroelectric Polarization in an Elementary Substance or Single-Element Compound. A technical paper titled “Two-dimensional ferroelectricity in a single-element bismuth monolayer” was published by researchers at National University of Singapore, Zhejiang University, Tianjin University, and University of Chinese Academy of Sciences. WebJun 29, 2024 · Numerical calculations indicate that a monolayer of Bismuth grown on SiC (0001) is a two-dimensional TI with a large energy gap. The researchers fabricated such a heterostructure and characterized it using scanning tunneling spectroscopy. The size of the experimentally measured gap was consistent with the calculations.
