Customer Application
The Nanostructure Group at the University of British Columbia's Quantum Matter Institute is investigating the optical properties of nanomaterials. For one experiment, the group uses two Zaber X-LRT0250AL-E08C linear stages mounted in an X-Z configuration as a part of a hyper-spectroscopic imaging apparatus. The high load capacity (5000 N maximum centered load and 120 Nm maximum moment load) of these stages allows the user to mount a number of components on the X-Z stage at the same time. Furthermore, the long travelling range of the stages gives the user additional flexibility in their experiments.
For a separate experiment, the Nanostructure Group uses a single Zaber X-LRT0200AL-E08C stage to generate a variable optical path delay between light pulses of an ultrafast pulsed laser. This allows users to create a laser pulse train with custom spacing between pairs of pulses from as low as 50 fs to as high as 1 ns. The low variability in pitch/yaw angles of the Zaber LRT stage allows users to perform multiple scans without repeated realignment.
About the Nanostructure Group at UBC's Quantum Matter Institute
The reduced dimensionality of nanostructures and the strong manifestation of quantum effects in them lead to interesting phenomena and a plethora of possibilities for studying fundamental physics and applying the knowledge gained to create new devices and enable new technologies. At its core, the Nanostructure Group's research is concerned with fabricating and exploring nanostructures with emphasis on the interaction of electrons, photons, and phonons with and in them. More specifically, the group investigates the movement of electrons over and through energy barriers (both within solids and into a vacuum), using excitation by heat, light, field, or other electrons, with phonons sometimes playing mediatory roles. They study both solid-state and vacuum devices, as well as the interface between the solid and vacuum, where many interesting things happen. The primary nanomaterial of interest is the carbon nanotube, although the group also works with nanostructures of other materials as warranted.
