The Van Der Pauw Method of Measuring Hall Effect to Determine Mobility, Carrier Type & Concentration
In this Lake Shore Academy: "How Does it Work?" video, we discuss the Hall effect and explore the procedure of conducting Hall effect measurements on a semiconductor material using Van der Pauw sample geometry and measurement method.
With an accurate measurement of the material resistivity and Hall effect, we are then able to calculate derived parameters such as carrier type (p-type or n-type), carrier concentration or carrier density, and mobility. These are the characteristics of most interest to the researcher trying to determine a material's suitability as a semiconductor.
As a compliment to this video, Lake Shore has developed the Hall Effect Measurement Handbook. This guide, written by Lake Shore Senior Scientist Dr. Jeffrey Lindemuth, reviews methods to measure the resistivity of materials, then discusses the theory of Hall measurements.
