Four-Probe Resistivity and Hall Voltage Measurements

Course Description

This workshop will give a Parametric Analyzer Overview with a focus on making bulk and surface resistivity measurements.  A mixture of resistivity measurement theory and live demonstrations will cover both the Analyzer operation and measurement techniques.  In addition, measurement challenges such as contact resistance, error sources, and low (< 100Ω) and high (10MΩ to TΩ) resistance samples will be addressed. The workshop will conclude with an open Q and A session to address individual concerns.
