Functional electronic materials

Functional Electronic Materials

In the Functional Electronic Materials unit, we conduct scientific research on state-of-the-art functional materials and nanostructures for next-generation electronic and photonic devices.

nanostructures, spintronic materials, perovskites Our aim is to obtain a better understanding of the fundamental physical properties of novel, functional materials, to manage a precise control of the material properties, and to fully explore the functionality of the studied materials for applications in future generation micro- and nano-electronics and photonics as well as in potential multifunctional devices and systems. In our research, we currently focus on a few main areas: novel spintronic materials, highly mismatched semiconductor nanostructures, complex perovskite materials and organic semiconductor materials.

We conduct our research by means of a large array of state-of-the-art optical, magneto-optical and spin-resonance spectroscopic equipment, and in close collaboration with researchers world-wide.

Efficient lasers at the nanoscale

In this study, Mattias Jansson and collaborators have investigated how the localization of excitons in tiny lasers fabricated in so-called nanowire structures can affect their performance.

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.

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 渭m from a Dilute-Nitride-Based Multishell Nanowire

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