Electron-hole and hole-hole bilayer systems with very narrow separations (5 nm and 7.5 nm) were generated in a single undoped GaAs/AlGaAs device. Observations conducted at zero magnetic field have shown enhanced electron-hole pairing, whereas signs of excitonic condensation have been observed in strong perpendicular magnetic field.

Controlling the property of electrons known as “spin” would allow for advances in everything from computers to medicine. Researchers in APL show they can manipulate spin with light. This is promising because we already have lots of ways to control light so we could take advantage of those to control spin.

Quantum dots are a promising source of single photons with anticipated uses in technologies such as linear optical quantum computers. To be useful, the frequency of the emitted photons must be tunable. This work combines electrical tuning and electrical excitation to create a compact array of all-electric single photon sources.

A type of laser called a VCSEL (for Vertical-Cavity Surface-Emitting Laser) is particularly good at detecting small amounts of gasses like carbon monoxide. But the laser has to be cooled to work, which limits how useful it is to small, inexpensive detectors. Now research in Applied Physics Letters has reported the first room-temperature VCSEL, paving the way to better gas detectors.
