Lake Shore Cryotronics will showcase products optimized for optical device and material research at next week’s San Diego SPIE Optics + Photonics exhibit.
On display in Booth 511 will be a TTPX cryogenic probe station for performing temperature-dependent, on-wafer measurements of samples under vacuum, the modular MeasureReady™ M81-SSM synchronous source measure system and a new, innovative SMU module for the system, and an ST-500 optical LHe/LN2 cryostat specially designed for use in microscopy, imaging, and high-spatial-resolution photoluminescence applications.
The tabletop TTPX is Lake Shore’s premium probe station design for electro-optical materials characterization. It supports optional backside optical illumination of a sample, which is ideal for examining photosensitive materials with topside metallization. The company also offers a full range of stations for photovoltaic material and semiconductor optoelectronic device research, with configurations available for:
- Electro-optical, DC, RF, and microwave measurements
- Temperatures as low as 1.6 K
- Integrated magnetic field
- Fiber optic probing and feedthroughs
- Load-lock and suitcase transfer options for delicate, air-sensitive samples
- Cryogen-free operation
The modular M81-SSM system is designed for highly synchronized DC, 100-kHz AC, and mixed DC and AC sourcing and measuring. The system can be ordered with balanced current source (BCS-10), voltage source (VS-10), current measure (CM-10), and voltage measure (VM-10) modules, as well as the unique, new SMU-10, which supports:
- Both DC and AC sourcing and measurement in a single module
- Lock-in detection capabilities optimized for nanoscale device characterization
- High measurement sensitivity (below 10 nanovolts/√Hz AC/lock-in and below 100 femtoamps DC)
All modules can be mounted directly on a probe station or cryostat, minimizing noise and unwanted effects from cabling and wiring to the sample. Setups can also be used for optical experiments, such as external quantum efficiency (EQE) measurements of solar cells and photodetectors, and light-current-voltage (LIV) testing of laser diodes and LEDs.
Also, at SPIE Optics + Photonics, Lake Shore representatives will be available to discuss the company’s:
- Full line of Environment by Janis cryostats and other cryogenic lab equipment, including the new automated Infinite Helium recirculating gas cooler system that enables a LHe cryostat to operate cryogen-free
- Hall effect measurement solutions, including the M91 FastHall™ controller, for analysis of solar cell, organic electronic, and transparent conducting oxide materials
- New MagRS magnetic research system with options to customize it for Hall effect, vibrating sample magnetometry, ferromagnetic resonance (FMR), and electron transport measurements
- Cryogenic sensors and instruments for stable, reliable low-temperature measurements
