Lake Shore Cryotronics will be at next week’s Compound Semiconductor Week (CSW) conference in Ann Arbor, MI, answering questions about systems and instruments for semiconductor research while showcasing the company’s new modular source measure system, FastHall™ Station, and a cryogenic probe station.
The all-in-one MeasureReady™ M81-SSM synchronous source measure system provides highly synchronized DC, 100 kHz AC, and mixed DC + AC sourcing and measuring — including both voltage and current lock-in measurement capabilities — for researchers exploring the electrical properties of new compound semiconductor materials.
Owing to its modular architecture, the M81-SSM allows signal and source amplifiers to be located as close as possible to the samples being characterized. By having both DC and AC sourcing and measurement in one instrument, the system can often eliminate the need for mixed-instrument setups, greatly simplifying the setup and operation of complex characterization configurations.
Additionally, the ultra-low-noise system is particularly optimized for low-level measurements of samples in cryogenic environments. At the CSW exhibit, Lake Shore’s setup will demonstrate how the M81-SSM instrument and its modules can be used to measure small photocurrents of a diode mounted in a Lake Shore Cryotronics VNF-100 cryostat, with the company’s MeasureLINK™ software managing the entire experiment.
Similarly, the FastHall Station on display will show how the same software can be used to execute and manage Hall effect measurements. Along with a PC and software for automating, charting, and analyzing the measurement, the fully integrated tabletop Hall system contains a 1 T permanent magnet, high-precision sample holder, and the company’s M91 FastHall measurement controller, which provides all the sourcing, measurement, and switching instrumentation needed to execute a complete measurement sequence — quickly and conveniently.
In addition to the FastHall Station, Lake Shore offers electromagnet-based 8400 Series Hall measurement systems. These complete systems are available with an AC field Hall option for characterizing materials with very low mobilities (down to 0.001 cm2/V s).
Also on display at CSW: the affordable TTPX cryogenic probe station for on-wafer probing of samples as a function of temperature. Lake Shore offers a full line of cryogenic and cryogen-free probe stations, with configurations available for DC, RF, and microwave probing of full and partial wafers at temperatures as low as 1.6 K and in fields to more than 2 T.
Plus, Lake Shore representatives will be discussing the company’s:
- MeasureReady MCS-EMP modular characterization systems, which are versatile electromagnet platforms that provide all the components needed for automated, variable field experiments
- Award-winning 8600 Series VSMs, which combine high sensitivity (15 nemu) and rapid measurement speed (10 ms/pt) in a simple-to-operate system for characterizing magnetic materials
- “Environment by Janis” cryostats, cryocoolers, and other lab cryogenic equipment
- Cryogenic measurement and control products, including cryogenic sensors, monitors, and controllers optimized for low-temperature material research
