German physicist
Mathias Michael Schubert (born 19 October 1966) is a German physicist,
[1] J. A. Woollam Distinguished Professor of Electrical and Computer Engineering at the
University of Nebraska-Lincoln ,
[2] and member of the
Nebraska Center for Materials and Nanoscience .
[3] He is a specialist in spectroscopic ellipsometry and has contributed to the development of blue and white
LED , fast processors and efficient biological and chemical sensors.

[6] He is also visiting professor at
Linkoping University and Associate Editor of the journal
Applied Physics Letters .

Early life and education
Schubert was born in
Jena ,
Bezirk Gera ,
East Germany . He graduated high school in 1986 with vocational education as
tool and die maker from the Keramische Werke in
Hermsdorf . After military service he studied physics at the
University of Leipzig until 1994.
[9] He received a fellowship from the
German Merit Foundation in 1995 for his doctoral research. In 1997 after earning his PhD he moved to the
University of Nebraska-Lincoln , where he worked on infrared ellipsometry developments for characterization of semiconductors. After return to the
University of Leipzig he obtained his
habilitation in 2003 in experimental physics.
Research and career
In 2000, Schubert was appointed Assistant Professor (Habilitant, C1) at
University of Leipzig , where he founded the Ellipsometry group.
[10] In 2005 Schubert was founding member of the German Association of Ellipsometry (Paul Drude e.V.).
[11] In 2005 Schubert was appointed associate professor at the
University of Nebraska-Lincoln , where he founded the Complex Materials Optics Network.
[12] In 2012 he became Full professor.
[1] Schubert's research focuses on broad spectral range optical characterization of organic and inorganic materials. He invented and developed spectroscopic
generalized ellipsometry broadly for characterization of arbitrarily anisotropic materials.
[13] His research team invented the
optical Hall effect for noncontact measurement of the
charge carrier
mass in
semiconductor materials and
thin film
heterojunctions .
[14]
[15] The
generalized ellipsometry concept permits analysis of optical properties of materials with all
crystal classes , particularly with low symmetry such as
orthorhombic ,
[16]
monoclininc ,
[17] and
triclinic .
[18] Schubert developed a general concept for modeling the optical properties of low-symmetry materials, the eigendielectric polarization model.
[19] In 2022, he demonstrated measurement of the
magnetic susceptibility
tensor in
electron paramagnetic resonance using
terahertz
ellipsometry
[20] and was part of a team describing a new form of coupled phonon photon states in low-symmetry materials.
