Lakeshore CRX-VF Cryogenic Vertical Field Probe Station
Overview
General Description
Vacuum probe station with vertical magnetic field and cryogenic temperatures for DC and RF probing of nanodevices.
Specifications
Probe station equipped with 4 DC probes and 2 RF (40 GHz) probes for probing samples up to 2" (50mm) diameter over a temperature range of ~10 K - 500 K and vertical (out of plane) magnetic field up to 2.5 tesla (derated to 2 tesla at 300 K). The chuck can be biased for body-biasing, and this biasing chuck can go up to 400 K.

Sample Requirements and Preparation
The RF probes in use have 150 um pitch.
DC probes have 25 um tip radius, but smaller (down to 3 um) tips can be purchased.
Standard Operating Procedure
