We will show what is the minimal size of these coverings and more ways how to construct ... -
Terahertzová vodivost Diracových elektronů
(Univerzita Karlova, Matematicko-fyzikální fakulta, 2020)Date of defense: 15. 7. 2020We explore the conductivity of Dirac electrons in the terahertz range, especially in graphene. We are trying to find a boundary condition that is suitable both for the eigen states around the Dirac points and the nanocrystalline ... -
Optické a magnetooptické vlastnosti tenkých vrstev topologického izolátoru Bi2Se3
(Univerzita Karlova, Matematicko-fyzikální fakulta, 2020)Date of defense: 15. 7. 2020Topological insulators have attracted intensive research interest in the field of material research in the last two decades. Their main advantage is that metallic conductive states are formed on their surface, in which the ... -
Refaktoring systému pro sledování kvality dat ve vrcholovém detektoru Belle II
(Univerzita Karlova, Matematicko-fyzikální fakulta, 2020)Date of defense: 15. 7. 2020This bachelor thesis deals with refactoring of a part of the Data Quality Monitoring (DQM) code for the Belle II vertex detector. In the second part of the thesis, monitoring of vertex detector half-shells movement over ... -
Demosaicing as an ill-posed inverse problem
(Univerzita Karlova, Matematicko-fyzikální fakulta, 2020)Date of defense: 15. 7. 2020Color information of a scene is only recorded partially by a digital camera.Specifically, only one of the red, green, and blue color components is sampled at each pixel.The missing color values must be estimated － a process ... -
Spektroskopie polovodičů s velmi vysokým časovým rozlišením
(Univerzita Karlova, Matematicko-fyzikální fakulta, 2020)Date of defense: 15. 7. 2020This thesis is aimed at building and optimization of a new experiment setup for measuring time-resolved transmittance using a pump-probe method. Test measurements were then conducted on a sample of SiV centers in diamond. ... -
