The working principle of the tungsten copper probe is based on the measurement of conductivity and resistance. When the probe contacts the sample, the current will pass through the probe and the sample to form a circuit. The magnitude and direction of the current depends on the conductivity and electric field distribution of the sample. By measuring the relationship between current and voltage, we can calculate parameters such as the conductivity and electron concentration of the sample. In addition, the probe station can also study the electronic behavior and band structure of the material by applying an external electric field or magnetic field.
