Background:

• The optical Hall effect is a phenomenon involving magnetic-field-induced dielectric displacement at optical wavelengths.
• It is analogous to the static electrical Hall effect and can be explained by extensions of the Drude model.

Purpose of the Study:

• To review and discuss physical model equations for calculating the optical Hall effect in semiconductor structures.

Main Methods:

• Review of physical model equations for optical Hall effect calculations.
• Definition and diagonalization of the optical Hall effect dielectric function tensor.
• Discussion of generalized ellipsometry, Mueller matrix calculus, and 4x4 matrix algebra.

Main Results:

• The optical Hall effect provides a contact-free method for characterizing electrical properties of semiconductors.
• Key parameters like effective mass, mobility, anisotropy, carrier type, and density can be determined.
• The study outlines theoretical frameworks and mathematical tools for optical Hall effect analysis.

Conclusions:

• The optical Hall effect is a powerful technique for semiconductor characterization, offering advantages over traditional electrical methods.
• Theoretical models and mathematical formalisms are presented for calculating and understanding the optical Hall effect.
