Application of metallic materials for selective growth
Němeček, Tomáš ; Rezek, Bohuslav (referee) ; Čechal, Jan (advisor)
The Si(100) surface and Ga surface phases up to 1 ML on their oxidation have been studied by XPS and LEED. The selective growth of Ga on the SiO2/Si structures fabricated by EBL has been analyzed using SEM and AFM methods. It was proved that Ga clusters grow in structures beside the oxide. The structure of alumina on Ni3Al(111) and NiAl(110) substrates was fully determined by combining the results of STM measurements and DFT simulations. It was determined the alumina/NiAl(110) does not form a suitable template for ordered Fe and Co clusters growth. However, the next research confirmed the alumina/Ni3Al(111) forms template appropriate to clusters growth purpose.

Atomic structure of FeRh(001) surface
Ondračka, Václav ; Bábor, Petr (referee) ; Čechal, Jan (advisor)
Alloy of iron-rhodium, Fe50Rh50, shows a low-temperature metamagnetic phase transition between its antiferromagnetic and ferromagnetic state. A detailed description of this transition using the tools of surface analysis has not yet been done. This bachelor’s thesis focuses on preparation and characterisation of the alloy’s clean surface using X-ray photoemission spectroscopy and low-energy electron diffraction. A flat field correction and a diffraction measurement callibration is done using a sample with known crystal lattice in order to quantify the diffraction results.

Preparation of elemental 2D materials
David, Jiří ; Čechal, Jan (referee) ; Kolíbal, Miroslav (advisor)
This thesis is focused on searching suitable experimental conditions for epitaxial growth of silicene, multilayer silicene and phosphorene, and their analysis by LEED and LEEM. Composition was analyzed by XPS. In the first part, a summary of literature research on properties and structure of these materials is presented. The second part describes experiments attemping to prepare these materials. Silicene was the only successfully-prepared material. It was imposible to reach suitable experimental conditions for multilayer silicene growth in the available experimetal setup. Deposition of phosphorus led only to formation of phosphorene precursor.

Calibration and interpretation of images measured by LEEM
Endstrasser, Zdeněk ; Novák, Jiří (referee) ; Čechal, Jan (advisor)
This thesis deals with the software development to calibration and interpretation of image data measured by a LEEM device. As the imaging technique is uniquely suited for in-situ studies of surface dynamical processes, the attention is mainly paid to methods enabling the evaluation of measurement time series. The phase correlation method based on Fourier transform of images is proposed to temperature shift correction between consecutive frames. The thesis describes the methods of additive and impulse noise filtering, image visualization, the filtration of secondary electrons and the determination of I-V curves from measured image data. Implemented methods are described not only in terms of their mathematical origin, but also with emphasis on the revealing of critical aspects associated with their use. The thesis also focuses on the application of the created algorithm to image data capturing the spatial and temporal evolution of 4,4’-biphenyl-dicarboxylic acid surface phases induced by sample annealing. Based on these evaluations, a suitable procedure is then determined to perform accurate detection and compensation of temperature shift said.

Construction Project for Implementation of Municipal Library in Slapanice
Hudcová, Natálie ; Doubek, Rostislav (referee) ; Nečasová, Barbora (advisor)
This thesis aims to formulate the construction technology project describing the municipal library in Šlapanice as a newly constructed building. The footprint plan of the designed object has the shape of the letter L. Part of the object facing towards the street serves for restaurant and cafe purposes, is single floored, and its roof is divided into two sections, starting with a gable roof followed by a flat roof. The building is located perpendicularly to the Riegrova street. The second part of the municipal library's building consists of two floors and is partially embedded in the slope. Its roof is divided into a gable roof and a flat roof as well. The purpose of this thesis is to develop a technical report on the construction technology project, a study describing the implementation of the main technological stages of the construction object, research of the transportation network, and the time and financial plan of the construction project. Further, this work presents the construction site equipment project, construction machines and mechanization proposal, technological regulations for the monolithic ceiling structure and trusses implementation, resource assurance plan, inspection and test plan, and health and safety plan for selected processes. Later, this thesis focuses on the itemized budget for the chosen technological processes of the construction object, the main lifting mechanism proposal and assessment, drawings related to selected technological regulations and LEED certification.
