Gerrit Rietveld 's shop designs in the Netherlands from 1922 to 1962

This essay investigates the shops as well as commercial buildings designed by Gerrit Rietveld in the Netherlands from 1922 to 1962, focusing on the relation between the interior and the exterior in each project. Gaining insight into his contribution to the history of shop designs. This research has been conducted through a combination of literature study, and the archive of Gerrit Rietveld in the Het Nieuwe Instituut in Rotterdam, and provides elaboration on themes as the designs of the shop front, the interior, and the connection between them. These themes are addressed through observation of the images, and drawings in the archive and other resources. The essay also provides a critical view for the role of those shops in history, and their influences on subsequent shop designs after that. AR2A011Architecture, Urbanism and Building Science

Giant Spin-Orbit Splitting in Inverted InAs/GaSb Double Quantum Wells

Transport measurements in inverted InAs/GaSb quantum wells reveal a giant spin-orbit splitting of the energy bands close to the hybridization gap. The splitting results from the interplay of electron-hole mixing and spin-orbit coupling, and can exceed the hybridization gap. We experimentally investigate the band splitting as a function of top gate voltage for both electronlike and holelike states. Unlike conventional, noninverted two-dimensional electron gases, the Fermi energy in InAs/GaSb can cross a single spin-resolved band, resulting in full spin-orbit polarization. In the fully polarized regime we observe exotic transport phenomena such as quantum Hall plateaus evolving in e2/h steps and a nontrivial Berry phase.QRD/Wimmer LabQuTech(OLD) Chair of Relation to Practice urQRD/Kouwenhoven La

Spin-orbit interaction in a dual gated InAs/GaSb quantum well

The spin-orbit interaction is investigated in a dual gated InAs/GaSb quantum well. Using an electric field, the quantum well can be tuned between a single-carrier regime with exclusively electrons as carriers and a two-carrier regime where electrons and holes coexist. The spin-orbit interaction in both regimes manifests itself as a beating in the Shubnikov-de Haas oscillations. In the single-carrier regime the linear Dresselhaus strength is characterized by β=28.5 meV Å and the Rashba coefficient α is tuned from 75 to 53 meV Å by changing the electric field. In the two-carrier regime a quenching of the spin splitting is observed and attributed to a crossing of spin bands.QRD/Kouwenhoven LabQuTechQRD/Wimmer La
