    Growth and Optical Properties of 2D Photonic Crystals Based on Hexagonal GaAs/AlGaAs Pillar Arrays by Selective-Area Metalorganic Vapor Phase Epitaxy

    We report on the growth of GaAs and GaAs/AlGaAs heterostructured hexagonal pillar arrays using selective area (SA) metalorganic vapor phase epitaxy (MOVPE) for the application of two-dimensional photonic cryst...

    Quantum dots fabricated by selective area MOVPE and their application to single electron devices

    A novel method of formation of uniform GaAs quantum dot (QD) structures, using selective area metalorganic vapour phase epitaxy (SA-MOVPE), and their application to single electron transistors (SETs) are demon...

    Intersubband Transition and Electron Transport in Potential-Inserted Quantum Well Structures and their Potentials for Infrared Photodetector

    The use of intersubband transition processes in superlattices for the detection of infrared radiations was first proposed and analysed in 1977 by Sakaki and Esaki[1] and later reinvented by Smith and Yariv[2]....

    High Resolution Transmission Electron Microscopy of GaAs/AlAs Hetero-Structures in the <110> Projection

    High resolution transmission electron microscopy (HRTEM) of GaAs/AlAs hetero-structures grown by molecular beam epitaxy (MBE) is carried out in the <110> projection. It is shown that GaAs and AlAs are distingu...
