Lake Shore Cryotronics will be showcasing a first-of-its-kind DC + AC source measure unit module with lock-in detection (SMU-10) and other innovative physics research products at next week’s APS Global Physics Summit in Anaheim, CA.

The SMU-10 is the newest module for the company’s MeasureReady™ M81-SSM synchronous source measure system. It builds on the M81-SSM platform’s ultra-low noise sourcing and measuring technologies, conveniently integrating I/V and DC/AC sourcing and measuring in a single compact module. It provides DC current, DC voltage, AC current, AC voltage, lock-in, and resistance measurement capabilities. 

Offering very low noise measurements with nano-volt and femto-amp precision, the SMU-10 is ideal for characterizing the ultra-low voltage regimes of nanoscale and 2D nanomaterial semiconductors. Plus, it provides increased measurement sensitivity by thermal and offset reduction through AC measurement capabilities, and synchronous/simultaneous sourcing and measuring removes sampling misalignment, making it well-suited for semiconductor I-V testing.

APS attendees who want to see an SMU-10 measurement can visit Lake Shore’s booth. The company will demo a measurement of a sample mounted in a TTPX cryogenic probe station.

Also on display will be:

• A demo version of the new fully automated Infinite Helium recirculating gas cooler system, which makes a liquid helium cryostat cryogen-free (shown attached to an ST-500 optical microscopy cryostat in the Lake Shore booth)
• Other Environment by Janis cryostats, including the closed-cycle, cryogen-free CCS-100 optical cryostat and the continuous flow ST-400 ultra-high vacuum (UHV) cryostat (ideal for use in beamline applications)
• The fully integrated CryoComplete system, which includes M81-SSM instruments, an LN₂ cryostat, a cryogenic controller, and software for 77 K to 500 K characterization applications
• The FastHall™ Station for rapid, convenient Hall analysis using patented FastHall technology as provided by the M91 FastHall controller (also shown: an insert for easily integrating the M91 into a Quantum Design PPMS^®)

In addition, representatives will also be answering questions about Lake Shore’s:

• Wide selection of cryogenic sensors, controllers, and monitors — with Lake Shore offering an early look at its next-generation cryogenic controller in its booth
• New electromagnet-based MagRS system, with a miniaturized replica of the system on hand showing how the various components work together to allow for VSM, FMR, and Hall effect measurements
• Full range of cryogenic probe stations for performing on-wafer DC or high-frequency measurements at temperatures as low as 1.6 K and in fields as high as 5 T under vacuum

In addition to the exhibit, Lake Shore will be participating in the APS conference, with the company’s Applications Team presenting on: 

• "Reducing Common-Mode Artifacts in 2D Material Measurements” at 3:36 p.m. Wednesday (Session MAR-N20), in 254B (Level 2) of the Anaheim Convention Center
• "Separating Density and Mobility Transients: Frequency-Multiplexed Hall Effect Method” at 9:48 a.m. Friday (Session MAR-W20), also in 254B (Level 2) of the convention center; this presentation relates to research co-authored by Northwestern University and ETH Zurich scientists
