Upcycling of light at the nanoscale

In this paper by Mattias Jansson and collaborators, they demonstrate how a semiconductor nanowire can efficiently absorb low energy light and convert it to light of a higher energy, a process which is called energy upconversion.

Spin injection and helicity control of surface spin photocurrent in a three dimensional topological insulator

In this paper, we show how a spin current can be injected from a conventional semiconductor, such as GaAs, to a topological insulator, Bi2Te3.

Record conduction-electron spin polarization achieved, exceeding 90% at room-temperature

We demonstrated generation of conduction-electron spin polarization exceeding 90% at room temperature in InAs quantum dots via remote spin filtering - the highest value reported in any semiconductor by any approach.

Anomalously strong second-harmonic generation in GaAs nanowires via crystal-structure engineering

In this work, we demonstrate highly efficient second-harmonic generation in subwavelength wurtzite (WZ) GaAs NWs, reaching 2.5x10-5 W-1 that is about 7 times higher than that of their zincblende counterpart.

Room-temperature polarized spin-photon interface based on a semiconductor nanodisk-in-nanopillar structure driven by few defects

We demonstrate high optical polarization inferring high electron spin polarization at room temperature in a 1D system.

Near-Infrared Lasing at 1 μm from a Dilute-Nitride-Based Multishell Nanowire

In this study, we demonstrate the NIR lasing at 1 μm from GaAs/GaNAs/GaAs core/shell/cap dilute nitride nanowires with only 2.5% nitrogen.

SIMARC - Swedish Interdisciplinary Magnetic Resonance Center

The Swedish Interdisciplinary Magnetic Resonance Center is a cross-disciplinary research center, aiming to bring together and facilitate idea and information exchanges between the disciplines that use Magnetic Resonance.
