Introduction

The Lakeshore probe system consists of 6 probes that can be used for electrical characterization of materials and devices. It has vacuum and temperature-dependent measurement capabilities.

Training

Contact Hema Movva or Amritesh Rai for training and certification. Scheduling is done via yahoo calendar, with preference for Banerjee group users.

Procedure

Vent and load sample
- Close Viton valve to turbo/scroll pump
- Vent using N2 hookup to ~ 800 psi
- Remove glass lid on probe station
- Mount sample
- Re-install glass slid if doing temp dependent or in vacuum measurements - for open air measurements, not necessary
- Pump down if temp dependent or in vacuum measurement

Measurement
- Check probe connections to B1500 or lock in amplifier, if using
- Land probes on sample or sample contacts in appropriate orientation (vdP or 4 point probe for sheet resistance measurements)
- Typically probes 1, 2, 3 and 4 are used for measurement - 5 and 6 are designed for RF measurements
