It is commonly believed that organic molecules are physisorbed on the ideal nonpolar surfaces of wide band gap insulators with limited variation in the electronic properties of the adsorbate molecule. On the basis of first ...

The mechanical analog to the topological insulators brings anomalous elastic wave properties which diversifies classic wave functions for potential broad applications. To obtain topological mechanical wave states with good ...

Solution-processable two-dimensional (2D) semiconductors with chemically tunable thickness and associated tunable band gaps are highly promising materials for ultrathin optoelectronics. Here, the properties of free charge ...

Topologically non-trivial surface states were reported first on ${\mathrm{Bi}}_{1-x}$Sb x bulk crystals. In this study we present transport measurements performed on thin ${\mathrm{Bi}}_{1-x}$Sb x -films (up to 24 nm ...
