Electrodeposition of thin tantalum layers from ionic liquids and measurement of their electrical properties
Svobodová, Ivana ; Boušek, Jaroslav (referee) ; Šimůnková, Helena (advisor)
The thesis is focused on the electrodeposition of tantalum from ionic solution 1-butyl-1- methylpyrrolidinium bis(trifluoromethylsulfonyl) imide, ([BMP]Tf2N) at 200°C and description of related transfer and kinetic phenomena on the interface between the ionic solution and working electrode. Furthermore, the electrodeposition of tantalum layers in different ionic solutions containing tantalum salts and especially in ([BMP]Tf2N) is introduced. In the last part of the thesis, results of cyclic voltammetry, surface analysis SEM and elemental analysis EDX are discussed. MIS (metal-insulator-semiconductor) structure was determined comprising porous anodic alumina as the insulator and semiconductive TaxOy on the top of the insulator. The electric conductivity of the MIS structures was studied by using amper-volt IV and CV characteristics. The results of the cyclic voltametry, impedance spectroscopy and chronoamperometry are discussed.

Metallization of technical plastics for lightweight traffic components with reduced fuel consumption
Sanetrníková, Dominika ; Boušek, Jaroslav (referee) ; Šimůnková, Helena (advisor)
The beginning of this thesis is dedicated to polymeric materials, which include plastics an composites. Plastics are shortly divided into two groups, thermoplastics and thermosets. The following part is the use of plastics and composites in traffic industry and briefly this work focuses on techniques of recycling of this materials. This work also focuses on the techniques of thin film deposition, electroless plating, electrodeposition as well and plating in the vacuum environment. special techniques of thin film deposition are also mentioned shortly. The coatings of polymer including cleaning and surface activation is introduced using various techniques including plasma treatment. The surface treatment of polyetheretherketone (PEEK) is included too. The final part describes performed experiments and discussion of results.

Electrical properties of nanostructured TaxOy for capacitive applications
Nováková, Tereza ; Boušek, Jaroslav (referee) ; Šimůnková, Helena (advisor)
Cílem diplomové práce bylo nastudovat a popsat mechanismy transportu náboje v tantalovém kondenzátoru. Práce obsahuje stručný teoretický úvod do problematiky kondenzátoru jako součástky a dále se zabývá jednotlivými mechanismy přenosu náboje jako je ohmická, Poole-Frenkel proudová, Schottkyho, tunelovací a emisní složka a také proudem prostorového náboje. V experimentální části byly měřeny ampér-voltové I/V, ampér-časové I/t a impedanční charakteristiky, jejichž data byla následně zpracována pomocí např. Mott-Schottkyho analýzy a byly vyhodnoceny elektrické parametry jako je aktivační energie, koncentrace dopantů, akumulační kapacita nebo potenciálová bariéra. Výsledky, vypočtené veličiny a naměřené hodnoty jsou diskutovány.

Bertolt Brecht's Dreigroschenroman in Czech translations
Šimůnková, Helena ; Veselá, Gabriela (advisor) ; Kloudová, Věra (referee)
My thesis is a comparison and translation analysis of two translations of the Dreigroschenroman, a novel by the renowned German author Bertolt Brecht. The first translation, by Jaroslav Zaorálek, was published in 1935 with the poems translated by Břetislav Mencák. The second translation, by Rudolf Vápeník, was published in 1973 with the poems translated by Ludvík Kundera. As of now, no other translation of the novel into Czech has been made. The empirical part of my thesis, in which the translations are analysed, is preceded by the theoretical part. In the theoretical part I present some basic facts about Bertolt Bercht's person, the Dreigroschenroman, the reception of Brecht's work in Czechoslovakia and the Czech Republic as well as abroad, and the Czech translators of the novel. I have attempted to place the author and his work into a proper literary, social and historical context. The theoretical part is divided into several chapters. Chapter One is an introduction to the topic and the structure and aim of my thesis. Chapter Two is a summary of the current state of research. I mention biographies of Bertolt Brecht, Czech master theses on Brecht's work, and relevant articles on this topic. Chapter Three is about the person of Bertolt Brecht. The first part of this chapter is a summary of his life, with a...
