Preparation of ultra sharp tips for STM TERS applications
 Šilhan, Lukáš ; Man, Ondřej (referee) ; Jan, Vít (advisor)
The goal of this bachelor thesis is preparation of Au tips by electrochemical etching. The theoretical part deals with comparison of microscopy techniques for materials surface characterization and Raman spectroscopy. The experimental part is focused on the settings of optimal etching parametres to gain appropriate geometry of fabricated tips. Function of tips is verified by evaluation of data gained by experimental measuring with this tips. Prepared tips are suitable for applications such as STM and TERS.

Mechanical and optical design of spectroscopic system for reactive ion etching system
 Šilhan, Lukáš ; Dostál, Zbyněk (referee) ; Šerý, Mojmír (advisor)
Measurement of absorption spectra of plasma during reactive ion etching enables characterization of etched species and control over the etching process. Aim of this diploma thesis is to design spectroscope with Czerny-Turner configuration for reactive ion etching system. Developed spectroscope achieves 1 nm resolution in 350-800 nm range. Device was tested during reactive ion etching of silicon.
