ABOUT OUR Special systems
A Hall effect system under photonic illumination is a detection or measurement device that simultaneously exploits:
the Hall effect, an electromagnetic phenomenon used to measure a magnetic field, current, or carrier density in a material; and
photonic excitation (laser, LED, pulsed or continuous light) designed to modify the electronic properties of the sensitive material.
Photonic illumination generates additional charge carriers in the semiconductor (electrons/holes), which enhances or modulates the Hall response.
These systems cover a wide range of applications for the advanced characterization of semiconductor materials and thin films.
Based on the Van der Pauw method and the exploitation of Lorentz forces, they allow for the simultaneous analysis of several electrical parameters with high precision, even under varying environmental conditions.
