We demonstrate that fringe fields stemming from nanostructured ferromagnets (FMs) provide the opportunity to manipulate spins in an underlying dilute magnetic semiconductor (DMS) heterostructure, both coherently and incoherently. Fringe fields from F

We investigated a hybrid structure consisting of microstructured Fe/Tb multilayer ferromagnets (FMs) and a ZnCdMnSe dilute magnetic semiconductor quantum well (DMS QW) by means of superconducting quantum interference device (SQUID) magnetometry and m

We demonstrate light emitting devices based on ZnO nanoparticles and realized without any additional organic support layers. Pure ZnO devices showed electroluminescence in the visible and the UV spectral range at voltages below 10 V. In order to faci

Semiconductor nanoparticles are attractive candidates for future large-area light emitting devices that are both costeffective and robust. We demonstrate a ZnO nanoparticle light emitting device realised without organic support layers. Tight layers w

A light emitting device with commercially available ZnO nanoparticles as an active layer was realised without the help of organic support layers. A tight ZnO nanoparticle layer with thickness of 500 nm was spin coated on the top of an indium tin oxid

Employing fringe fields from microscale Fe/Tb multilayer ferromagnets (FMs) with remanent out‐of‐plane magnetization, we are able to define a local, remanent carrier spin polarization in an underlying ZnCdMnSe dilute magnetic semiconductor quantu

We report on room-temperature electroluminescence from an all-inorganic light emitting device based on spin-coated ZnO nanoparticles. A tight submicron thick layer was fabricated on a fluorine doped tin oxide glass as a substrate using commercially a

We demonstrate a method to electrically manipulate the spin polarization in a semiconductor on a micrometer length scale and a submicrosecond time scale. A variable magnetic field induced by a microscale current loop magnetizes the Mn2+ ions in a CdM

We present the ability to manipulate spin states in a semiconductor on a sub-micrometre length scale via the magnetic fringe fields of microstructured magnets. Fe/Tb multilayers with remanent out-of-plane magnetization induce a remanent, vertical mag
