  • Current Research Interests

    We are interested in utilizing unique physical properties of various low dimensional (D) nanomaterials, such as 2D van der Walls layered materials, 1D nanorods (and nanopillars), and 0D quantum dots, as key building blocks for fabricating high performance and new functional semiconductor optoelectronic devices. Details of the current research interests are:

    • Metal-organic chemical vapor deposition and chemical vapor deposition of high qualitysemiconductor microstructures and nanostructures, 2D van der Walls layered materials, and their hybrids.
    • Fabrications of high performance optoelectronic devices, such as light emitting diodes, solar cells, and sensors.
    • Strain engineering of semiconductor heterostructures and quantumstructures using nanofabrication and/or heteroepitaxial growth.
    • Diverse device applications including transferable and wearable devices, full-color inorganic microdisplays, augmented reality, quantum computing and communications, neural probes, and so on.
