Cyclotron resonance of Dirac electrons in bismuth selenide
 Hlavička, Ivo ; Dubroka, Adam (referee) ; Bartošík, Miroslav (advisor)
Bismuth selenide belongs to a class of topological insulators---materials characterized by a intriguing electronic band structure, with a characteristic Dirac conical band on the surface. In this master thesis, the optical response of this material is explored in the infrared spectral range and in a broad range of magnetic fields. We mainly focus on the absorption of light due to free charge carriers having, when the magnetic field is applied, a form of cyclotron resonance. We find that the experimentally observed response is consistent with expectations for massive electrons in bulk rather than massless particles on the surface.
