Dr. Marx working on ebeam system

The experimental solid state physics lab is devoted to the synthesis and characterization of bulk, thin film, and nanocrystalline materials. Characterization includes structural, electrical, and thermal properties. Currently focus is on energy conversion devices including photovoltaics and thermoelectrics, particularly those incorporating novel nanoscale technologies.

Facilities include: a UHV e-beam thin film deposition system, a 1200 C tube furnace, a hydraulic press, a diamond saw, a planetary ball mill, a metal evaporation system, and an assortment of advanced electronic and vacuum equipment.
