Topological insulators are one of the most puzzling quantum materials. Their edges are electron superhighways where electrons flow with no loss, while the bulk of the material blocks electron flow - ...

A light pulse redirects electrons in an ultrathin layered material, creating a stable new state without heat or damage and suggesting a low-energy route to faster electronics. (Nanowerk Spotlight) ...

A new method by Penn State researchers conveniently changes the direction of electron flow in materials that exhibit the quantum anomalous Hall (QAH) effect — a phenomenon in which the flow of ...

A new study has found evidence of a new phase of matter predicted in the 1960s: the excitonic insulator, which has been keenly pursued by condensed matter physicists and 2D material scientists. The ...

(Nanowerk News) An study has found unusual insulating behaviour in a new atomically-thin material – and the ability to switch it on and off. Materials that feature strong interactions between ...

The extended Su–Schrieffer–Heeger (SSH) tight-binding model was employed to accurately elucidate the electron transport behavior in donor polymer. The time evolutions of net charges on each site shown ...

An atomic force microscope can be used as a single-electron current meter, according to new experiments by researchers at IBM. The technique, which measures the energy levels of single molecules on ...
