Limitation exposed in promising quantum computing material: Metallic surfaces no longer protected as topological insulators become thinner

ScienceDaily   -   General News Websites

Physicists have theorized that a new type of material, called a three-dimensional (3-D) topological insulator (TI), could be a candidate to create qubits for quantum computing due to its special properties. A study found that when the TI's in...

Resistance is utile: Magnetite nanowires with sharp insulating transition

ScienceDaily   -   General News Websites

Scientists have produced Fe3O4 nanowires on 10-nm length scales by deposition on an MgO substrate. When cooled to 110 K, the nanowires showed a sharp Verwey transition -- greater resistivity resulting from a change in crystal structure. This switc...
