Epitaxial and Low dimensional Nanomaterials Group

Molecular Beam Epitaxy is a physical vapor deposition (PVD) technique for epitaxial growth of films by the interaction of molecular or atomic beams at the surface of a heated crystalline substrate under Ultra-High vacuum (UHV). Our group uses plasma-assisted molecular beam epitaxy to grow III-Nitride based light emitting diode (LED) and laser diode (LD) structures.

Equipment

  • Plasma-Assisted Molecular Beam Epitaxy (MBE) System.
  • In-situ Reflection High Energy Electron Diffraction (RHEED) and Spectroscopic Ellipsometer.

Recent activities

  • Epitaxial growth of Gallium Nitride (GaN) on sapphire substrates by MBE.
  • Development of Carbon activated Al2O3 radiation sensors.
