The Van der Pauw Experiment (VDX-01) setup is a specialized laboratory apparatus used to determine the resistivity and Hall coefficient of thin, flat samples of arbitrary shape using the Van der Pauw method. This technique is widely employed in semiconductor research and material science due to its accuracy and efficiency for characterizing electrical properties of materials.
The VDX-01 includes a sample holder with four symmetrical probe contacts, a constant current source, and a digital microvoltmeter for accurate voltage measurement. The system is designed for low-resistance and high-resistance samples and is capable of supporting temperature-dependent measurements when connected to external thermal setups.
This compact and easy-to-use instrument is ideal for university labs, research institutes, and R&D centers for studying carrier concentration, mobility, and anisotropic conduction properties in semiconductors.
