Adaptation of the UHV SEM system for growth and characterization of nanostructures
 Skladaný, Roman ; Mach, Jindřich (referee) ; Páleníček, Michal (advisor)
This bachelor thesis presents mechanical design of an objective protection of ultrahigh vacuum scanning electron microscope (UHV SEM), which is a part of a complex modular UHV system used for growth, observation and characterisation of nanostructures. Main physical and technical working principles of the UHV SEM system are explained. Furthermore, adaptation of a Knudsen cell used for growth of ultrathin layers in the UHV SEM system is described. Finally, a mechanical design of a shutter reducing overheating and contamination of objective during in situ growth and observation of nanostructures is drafted. The objective shutter also protects the sample from ambient heat radiation in case that sample is cooled to cryogenic temperatures.
