Lake Shore Cryotronics will be discussing their cryogenic probe stations and a new terahertz (THz) frequency contact probing arm option at the SPIE Optics + Photonics Exhibition in San Diego, 30 Aug. - 1 Sept.

Lake Shore cryogenic probe stations offer a convenient, reliable way to measure electro-optical, DC, RF or microwave properties of early-stage devices and materials, including novel photovoltaic materials, at temperatures as low as 1.6 K. Applications include research into optical properties of nanostructured materials, the electro-optical spectroscopy of charge carriers, and semiconductor optoelectronic devices and materials.

A number of probe station versions are available from Lake Shore, including cryogen-free CCR (closed-cycle refrigerator) models and an affordable, entry-level version (the Model TTPX), which will be on display in their booth during the exhibition. Also available: versions equipped with a superconducting magnet or electromagnet for investigating magneto-transport parameters of ferroelectric and magneto-resistive devices.

In addition, for those interested in performing high-frequency contact measurements as a function of temperature and field in their cryogenic probe station, Lake Shore will be answering questions about their THz-frequency contact probing arm option. This unique option enables S-parameter characterization via precise on-wafer probing of millimeter wave devices and materials at 75 to 110 GHz (WR10) or 140 to 220 GHz (WR5.1) frequencies in a cryogenic environment. This option is particularly valuable to researchers developing next-generation electronics, including new MMIC, MEMS, LNA, and THz detector devices, and radio astronomy components.
