    Influence of microwave photo-excitation on the transport properties of the high mobility GaAs/AlGaAs 2D electron system

    We examined the influence of the microwave power on the diagonal resistance in the GaAs/AlGaAs two dimensional electron system (2DES), in order to extract the electron temperature and determine microwave induc...

    Single-spin CCD

    The electron spins in a linear array of three quantum dots can be manipulated, shuttled and read out individually with high fidelity, resembling the functioning principle of a CCD (charge-coupled device).

    Linear Polarization Rotation Study of the Microwave-Induced Magnetoresistance Oscillations in the GaAs/AlGaAs System

    Microwave-induced zero-resistance states appear when the associated B-1-periodic magnetoresistance oscillations grow in amplitude and become comparable to the dark resistance of the two-dimensional electron syste...

    Microwave Reflection From The Microwave Photo-Excited High Mobility GaAs/AlGaAs Two-Dimensional Electron System

    We examine the microwave reflection from the high mobility GaAs/AlGaAs two-dimensional electron system (2DES). Strong correlations have been observed between the microwave induced magnetoresistance oscillation...

    Long-distance coherent coupling in a quantum dot array

    Controlling long-distance quantum correlations is central to quantum computation and simulation. In quantum dot arrays, experiments so far rely on nearest-neighbour couplings only, and inducing long-distance c...

    Binding of Electrons and Holes at Quantum Wires Formed by T-Intersecting Quantum Wells

    Calculations are made of the properties of quantum wires formed by two or more GaAs/AlGaAs quantum wells intersecting at right angles in a T-configuration.This T-intersection geometry has taken on additional r...

    Single-Mode Stimulated Emission in a Quantum-Wire Laser Fabricated by Cleaved-Edge Overgrowth

    We have used the molecular beam growth technique, we call Cleaved Edge Overgrowth to fabricate highly efficient lasers, which operate in the ID quantum limit. The active region of our laser consists of quantum...
