Lake Shore Cryotronics will exhibit its materials characterization solutions, including its prototype terahertz (THz) system, at booth 623 at SPIE Optics + Photonics, August 27-29 in San Diego. In addition to the new THz system, Lake Shore offers probe stations and Hall measurement systems (HMS) for complex measurements under variable temperature and magnetic field conditions.
The SPIE Optics + Photonics technical program will focus this year on nanoscience and solar energy, among other topics. Researchers in spintronics, metamaterials, graphene, thin-film solar technology and other applications discussed will have the opportunity to see a demonstration of Lake Shore’s THz material characterization system. The prototype system uses non-contact, THz-frequency energy to enable researchers to explore phenomena in emerging electronic materials over a range of temperatures and magnetic fields.
Lake Shore has designed the system for use by material developers, including those in solar cell research. THz light specifically can be used to characterize electronic transport in transparent conductive oxides, including zinc oxide, which can be important in future solar cell development. In addition, THz spectroscopy offers particular potential for characterizing dielectric materials and certain multi-layer materials because terahertz light can pass through and pick up information from all of the layers.
Several key research facilities in the U.S. are currently using alpha units of the THz system to gain valuable insight into molecular solids, thin films and other semiconductor devices. Earlier this year, Lake Shore was awarded an Air Force STTR Phase I grant in support of the project.
The Lake Shore Model 8404 AC field system can be ordered with unique AC field Hall measurement capability, which enables users to characterize materials with Hall mobilities down to 0.001 cm2/V s, lower than is possible using traditional DC field Hall measurement techniques. The company’s cryogenic probe stations enable reliable, unattended measurements of electrical, electro-optical, DC, RF and microwave properties of materials and test devices at cryogenic temperatures and under the application of magnetic fields up to 30,000 G.
