Copy Citation
An oscillation in the conductivity of a material that occurs at low temperatures in the presence of very intense magnetic fields, the Shubnikov–De Haas effect (SdH) is a macroscopic manifestation of the inherent quantum mechanical nature of matter. It is often used to determine the effective mass of charge carriers (electrons and electron holes), allowing investigators to distinguish among majority and minority carrier populations. The effect is named after Wander Johannes de Haas and Lev Shubnikov.

- Since defects in the sample will affect the position of the Fermi energy EF, this is strictly speaking an approximation. Any influence of defects and of temperatures above 0 K is neglected here for now.
- The number of edge channels i is closely related to the filling factor ν = 2 ∙ i. The factor 2 is due to spin degeneracy.
- Relationship (3) is expressed in SI units. In CGS units, the same relationship reads [math]\displaystyle{ \Delta\left(\frac\right) = \frac. }[/math]
