Device and materials characterization can be challenging, especially when dealing with low-level source and measurement values. This is particularly the case when characterizing low-resistance/superconductive samples, high-resistance materials, and samples with large differences in states, like topological insulating materials.

This webinar will introduce practical steps that can ensure high-quality and repeatable measurements.

Topics will include:

• Proper wiring, guarding, and shielding
• Similarities and differences between AC/lock-in and DC measurement techniques
• Filtering and its effects on data
• Key factors for successful measurements at cryogenic temperatures
• Single-ended vs. differential measurements
