Facilities & Equipment

Laboratories:

The Laboratory of Quantum Materials for Sustainable Technologies is located in the Engineering Teaching Center (ETC) building (ETC 7.108, 7.158, 1.104, 1.204B) of the main campus and the Microelectronic and Engineering Research Building (MERB 2.508 & 2.510) of the J. J. Pickle Research Campus. ETC 7.108 is equipped with a Labcono chemical fume hood and a wet sink. ETC 7.158 is equipped with a dropdown hood. ETC 1.104 houses an Omicron ultrahigh vacuum (UHV) scanning tunneling microscope (STM)/atomic force microscope (AFM). ETC 1.204B is an optics lab for inelastic light scattering measurements. MERB 2.510 is equipped with a Hamilton chemical fume hood, two wet sinks,, gas lines connected to hydrogen and methane cylinders located in a separate gas bunker below the lab, and exhaust lines. MERB 2.508 and 2.510 are located above the class-100 clean room facility on the first floor of the building.
