Mercury: HV/UHV System
Mercury is a HV/UHV system designed to study organic monolayers bound to the surfaces of liquid Hg and Ga, and their solids just below the melting point. This instrument is used to study the role of the substrate in accommodating (i.e., relaxing) excess energy. It uses infrared spectroscopy and impedance spectroscopy to probe the effects of electron-induced damage to these films.
