Lake Shore Cryotronics will be at next week’s SPIE Optics + Photonics exhibit in San Diego demonstrating products optimized for optical material and device research.
On display in Booth 409 will be the affordable, tabletop TTPX cryogenic probe station for performing temperature-dependent, on-wafer material or device measurements under vacuum; the modular M81-SSM synchronous source measure system for highly synchronized DC, 100 kHz AC, and mixed DC + AC sourcing and measuring; and the compact ST-500 Environment by Janis optical cryostat.
The TTPX station is Lake Shore’s premium 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 wide range of stations for photovoltaic material and semiconductor optoelectronic device R&D, including configurations available for electro-optical, DC, RF, and microwave measurements, temperatures as low as 1.6 K, integrated magnetic field, and cryogen-free operation. Also available: fiber optic probing and feedthroughs, and load-lock and suitcase transfer options for delicate, air-sensitive samples.
The M81-SSM system, which can be used to provide an excitation source for measurements performed in a probe station as well as a cryostat, features remotely mountable modules capable of providing combined DC+AC voltage/current outputs with very low noise levels for highly sensitive device characterization.
The multichannel lock-in measurement system can, for example, be set up to stimulate and measure small photocurrents in a photodiode device mounted in a cryostat. The modular architecture of the M81-SSM allows for signal and source amplifiers to be mounted directly on the cryostat, minimizing noise and unwanted effects from cabling and wiring to the sample. Similar setups can be used for other optical experiments, such as external quantum efficiency (EQE) measurements of solar cell and photodetector devices.
Also at SPIE Optics + Photonics, Lake Shore representatives will be available to discuss the company’s:
- Full line of Environment by Janis cryostats, cryocoolers, and other lab cryogenic equipment, including recirculating gas cooler (RGC) options for cooling liquid helium cryostats without the need for liquid cryogens
- Hall effect measurement solutions, including the M91 FastHall™ controller for faster, more precise Hall 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, and ferromagnetic resonance (FMR) measurements
- Cryogenic sensors and instruments for stable, reliable low-temperature measurements
