Lake Shore to Discuss THz Characterization and High-Frequency Probing at IRMMW-THz

Lake Shore Cryotronics, a leading innovator in solutions for measurement over a wide range of temperature and magnetic field conditions, announced that it will be exhibiting solutions for high-frequency material characterization at the 39th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), Sept. 14–19, in Tucson, Ariz. Lake Shore specifically will discuss its fully integrated Model 8501 THz system for material characterization and its work toward developing THz-frequency solutions for cryogenic probe station-based measurement.

A non-contact spectroscopic platform, the Model 8501 enables researchers to more easily study research-scale electronic and magnetic materials with resonances in the THz regime. It uses uniquely designed continuous wave THz (CW-THz) emitter and detector components, supporting the ability to measure at 200 GHz to 1.5 THz frequencies and spectral resolution of better than 500 MHz.

Because the system includes a high-field cryostat and superconducting magnet, material responses can be measured across a range of temperatures and field strengths. These capabilities benefit research of materials at low temperatures at an early stage, when high magnetic fields (up to 9 T) may be required.

The Model 8501 system also includes intuitive management and analysis software, enabling quick setup of measurement profiles, automated measurement runs and real-time visualization of collected data. To see a demo of the software, IRMMW-THz attendees can stop by Lake Shore’s booth (#14). Also during the conference, Lake Shore will be conducting a poster session relating to field- and temperature-dependent thin film CW-THz characterization. This session will occur Thursday, Sept. 18, from 5:30 to 7 p.m. in the South Ballroom.

Separate from its THz material characterization solution, Lake Shore will also be discussing its most recent efforts toward developing a THz-frequency, on-wafer contact probing solution for cryogenic probe stations. This initiative is a collaboration of Lake Shore with several companies and university researchers. The goal is to enable high-speed device probing and performance measurements at variable temperatures and magnetic fields for next-generation electronics R&D. Conference attendees can learn more about this industry/university collaboration and see a prototype of Lake Shore’s cryogenic THz probe arm assembly by visiting the Lake Shore booth.

The company will also answer questions about its complete line of industry-leading cryogenic probe stations during the conference. These platforms enable non-destructive probing of materials and test devices as a function of temperature and field, whether 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.
