    An entangled-light-emitting diode

    For optical quantum computation and related information technologies to fulfil their promise, they will require a source of entangled photons that can be delivered efficiently on demand. Existing entangled-lig...

    Quantum dots for single photon and photon pair technology

    The excitation of a quantum dot from its ground state depends on the probabilistic nature of carrier capture, and thus radiative decay can occur via a multi photon cascade. It is also possible that non-radiati...

    Off-axis electron holography of focused ion beam milled GaAs and Si p-n junctions

    Si and GaAs p-n junctions have been characterised in the transmission electron microscope using off-axis electron holography. Focused ion beam milling was used to prepare parallel-sided membranes with thicknes...

    Growth Temperature Dependence of Size Distribution of Self-Assembled Inas Quantum Dots on Gaas(001): From Diffusion-To Strain-Limited Growth

    We have investigated the molecular beam epitaxy (MBE) growth of buried InAs quantum dots on GaAs (001) surface, as a function of deposition temperature, by transmission electron microscopy (TEM) and photolumin...
