Lake Shore exhibiting probe stations and THz materials characterization system at EuMW

In booth 206 at the 44th European Microwave Week (EuMW) conference in Rome, Italy (7–9 October), Lake Shore Cryotronics Inc of Westerville, near Columbus, OH, USA, which makes scientific sensors, instruments and systems for measurement and control under extreme temperature and magnetic field conditions, is exhibiting its platforms for the study of devices and materials using high-frequency measurement.

Platforms include Lake Shore’s probe stations for non-destructive probing of materials and test devices, for the study of electrical, magneto-transport, DC, RF or microwave properties. They are particularly useful for carbon-based nanotube (CNT), graphene, MEMS, gallium nitride (GaN), silicon germanium (SiGe), superconducting device and organic semiconductor research.

Lake Shore probe stations are designed specifically for on-wafer probing and measurement of device samples as a function of temperature and field. Interrogating samples at cryogenic temperatures and in high magnetic fields can reveal certain mechanisms of novel materials, particularly in semiconductor and nanoscale device research. Low-temperature operation is becoming increasingly important in the development of new electronic devices, including high-speed SiGe-based transistors, says the firm.

Lake Shore offers cryogen-free CCR probe stations and liquid cryogen models, as well as probes, sample holders and other options to enable the configuring of a station for a specific application. These include ground-signal-ground (GSG)-style probes for 40GHz or 67GHz frequency ranges and designed for optimum microwave measurement performance at cryogenic temperatures.

In addition, Lake Shore is currently working with several companies and university researchers to develop terahertz-frequency, on-wafer contact probing for cryogenic applications. The goal is to enable high-speed device probing and performance measurements at variable temperatures and fields for next-generation electronics R&D.

Also at EuMW, Lake Shore is discussing its turnkey Model 8501 THz system for non-contact characterization of materials at variable temperature and in high field. This complete platform includes management and analysis software and features an integrated high-field cryostat and uniquely designed continuous wave (CW) THz emitter and detector components. Supporting the ability to measure at 200GHz to 1.5THz frequencies with spectral resolution of better than 500MHz, the system’s CW-THz spectroscopy can reveal properties that other techniques miss because many phenomena have been found to align with these frequencies, says Lake Shore.
