Facilities

Our unique ultrahigh vacuum interconnected deposition and analysis facility allows for the growth of epitaxial metallic compounds and semiconductors by molecular beam epitaxy (MBE) and chemical beam epitaxy (CBE) techniques and characterization in-situ with variable temperature scanning tunneling microscopy (VTSTM), angle-resolved photoelectron spectroscopy (ARPES), reflection high energy electron diffraction (RHEED), low energy electron diffraction (LEED), Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS). Other analysis techniques such as Rutherford backscattering (RBS), transmission electron microscopy (TEM) and X-ray diffraction are used to study the grown structures.
