Technology Description:

Material Class:

Conductive and partially conductive solids

Technology Description:

Hall effect measurements are employed to study the details of conduction in semiconductors and other materials. Such electronic properties include the sheet resistance, doping type/prevailing carrier type, carrier concentration, carrier mobility and the effect of a magnetic field.
