20150915_095035

A home-built open aperture ns Z-scan, attached to a pulsed ns (Continuum Surelite II-10) laser (Shared with facilities at the Duke Energy Innovation Center), for measuring non-linear optical properties

LSR3

Linesis LSR 3 Using the Linseis LSR-Platform, thermoelectric materials in the form of solid material as well as in the form of thin films can be characterized almost completely. In the basic version – LSR-3, both the Seebeck-Coefficient and the Electrical Conductivity (or resistivity) of solid materials can be measured fully automatically and simultaneously up to a maximum temperature of 1500°C. It also capable of measuring cross-plane temperature-dependent Thermal Conductivity (Shared with facilities at Duke Energy Innovation Center)
