Welcome to the homepage for the Scanning Tunneling Microscopy (STM) Laboratory at UNT. As our name implies, we use Ultra-High Vacuum (UHV) STM to study the atomic and electronic structure of carbon-based materials, such as carbon nanotubes and diamond films. Our other UHV techniques include:

• Low-Energy Electron Diffraction (LEED),
• Auger Spectroscopy, and
• Temperature Programmed Desorption.

We also have several ambient environment equipment in our lab, including:

• Raman Spectroscopy, 
• air STM, and
• Atomic Force Microscopy (AFM).

    We are currently investigating the field emission properties of carbon nanotubes and diamond films, and the etching & growth of epitaxial diamond films at the atomic scale. Our goal is to develop carbon films for flat panel display applications, and to understand the diamond etching and growth mechanisms at the atomic scale, which are presently unknown.
