A versatile custom-built contact switching device for multi-purpose electrical transport measurements
Abstract This work outlines the assembly of a cost-effective and straightforward apparatus designed to automate contact switching for electrical transport measurements. We report example of applications for this custom device and showcase its versatility by employing it for electrical resistivity and Hall effect measurements following the van der Pauw method on oxygen-deficient strontium titanate single crystals, measurements on compressed bismuth using the Montgomery method, and measurements on fresh cleaved Highly Oriented Pyrolytic Graphite using a multi-line electrode configuration.
