TL;DR: In this article, the Hall voltage of a two-dimensional electron gas, realized with a silicon metal-oxide-semiconductor field effect transistor, was measured and it was shown that the Hall resistance at particular, experimentally well-defined surface carrier concentrations has fixed values which depend only on the fine-structure constant and speed of light, and is insensitive to the geometry of the device.

TL;DR: In this article, the authors present experimental results and a supporting theory, showing that a one-dimensional system in which transport is ballistic possesses a quantised resistance, h/2ie2, where i is the number of occupied 1D sub-bands and the spin degeneracy is two.

TL;DR: Electroluminescence from a single quantum dot within the intrinsic region of a p-i-n junction is shown to act as an electrically driven single-photon source for applications in quantum information technology.

TL;DR: By studying the terahertz pulse shape in the time domain, TPI is able to differentiate between diseased and normal tissue for the study of basal cell carcinoma (BCC) and inflammation and scar tissue.

TL;DR: The behavior of a laterally confined quantum dot in close proximity to a one-dimensional channel in a separate electrical circuit is investigated, finding the activation energy of transport through the dot is much lower than expected.
