Our current research is in to the behavior of 2D plasmons, 2D electronic behavior, and 2D magnetic behavior in specially prepared surfaces and thin films.

Our tools are:

1. Momentum and energy-space photoelectron spectroscopy using uv synchrotron radiation.

2. Atomic core-level magnetic dichroism using x-ray synchrotron radiation.

3. Very-high resolution Fermi surface studies using synchrotron undulator radiation.

4. In-situ uhv growth, using MBE and characterization, using surface science techniques, of ultrathin-film, novel electronic and magnetic materials.

5. Magneto-optical behavior and spin transport processes in magnetic alloys and finite-size nanostructures.

6. Scanning-probe microscopy and spectroscopy of stongly-correlated electronic effects due to narrow bands at semi-conductor surfaces and interfaces.

7. STM tip-induced physical processes: tunneling; electronic and vibronic excitations; light-emission; surface and molecular modification.

8. Electron spin injection and transport using ballistic electron emission (BEE).

9. Molecular electronics in carbon nanostructures: buckey balls; nanotubes; graphene molecules.

This research area provides opportunities for undergraduate research.
