Lake Shore to discuss high-frequency probing, characterization technology at IMS
Lake Shore at IMS 2015

Lake Shore Cryotronics will be exhibiting May 19 – 22 at the IEEE MTT International Microwave Symposium (IMS) in Phoenix, educating attendees on platforms for variable temperature based research of devices and materials using high-frequency measurements.

Lake Shore will be available at Booth 215 to discuss, among other products, their industry-leading cryogenic probe stations. These stations, designed for on-wafer probing of device samples as a function of temperature and field using RF, microwave, magneto-transport, or DC measurements, are particularly ideal for CNT, MEMS, GaN, or superconducting device research. Interrogating samples at cryogenic temperatures and in high field can reveal certain mechanisms, particularly for semiconductor device research. For attendees wanting to see a Lake Shore probe station up close, the company will have its tabletop Model TTPX set up in its booth.

Lake Shore offers a number of sample holder and probe options, including GSG style probes for 40- or 67-GHz ranges. Plus, later this year, the company plans to introduce a unique THz-frequency contact probing arm for cryogenic applications. This option will enable precise on-wafer probing of millimeter and sub-millimeter wave devices and materials at THz frequency bands. With this option, researchers will be able to perform high-speed measurements as a function of variable temperatures and high field for next-generation electronics R&D. Preliminary THz probe measurement results will be reported at the EuMW conference in Paris in September.

In addition, for IMS attendees interested in a non-contact spectroscopic platform for characterizing materials with resonances in the THz regime, Lake Shore will be discussing the new Model 8501 THz system. The Model 8501 is the first affordable and fully integrated system specifically tailored for characterization of research-scale materials.

The 8501 system supports the ability to measure at 200 GHz to 1.5 THz frequencies and spectral resolution of better than 100 MHz, and no special optics knowledge is required; all of the calibrations of THz components have already been done. The system also features intuitive software for fast setup of measurement profiles, automating measurement runs, and visualizing collected data in real time. Because the system includes a variable-temperature flow cryostat and superconducting magnet, THz transmission can be measured across a range of temperatures and field strengths. These capabilities benefit early-stage materials research, when exploring material responses while varying the environmental conditions may be required.
