Efeito do carbono na formação de defeitos em silício Czochralski / Effect of carbon in the formation of defects in Czochralski silicon.

Furtado, Wagner Wilson 14 June 1991 (has links)
Neste trabalho é estudado o efeito do carbono na formação de defeitos em silício Czochralski crescido na direção em amostras submetidas a tratamentos térmicos variados. Medidas de espalhamento difuso de raios-X, espectroscopia de infravermelho, medidas de resistividade, topografia de raios-X e microscopia eletrônica de transmissão mostraram que os defeitos nas amostras \"como crescidas\" podem ser relacionados com os microdefeitos tipo B. Tratamento térmico a 450ºC mostrou a presença de vacâncias nas amostras com baixa concentração de carbono enquanto que nas amostras com alta concentração de carbono ocorre a inibição da formação dos doadores térmicos (\"Thermal Donors - TD\"). Os resultados confirmam os modelos de Newman e Mathiot para a geração dos TD. Para tratamento térmico a 650ºC o carbono promove a formação de Novos Doadores (\"New Donors - ND\"). Os resultados mostram que estes defeitos são de natureza predominante de vacância e concordam com os modelos de geração que envolvem átomos de oxigênio substitucional. Os doadores observados a 550ºC puderam ser relacionados aos Novos Doadores Térmicos (\"New Thermal Donors - NTD\") observados por Kamiura et al.. / Effect of carbon concentration upon defect formation in oxygen rich Czochralski grown silicon has been investigated by combining various furnace thermal anneals. Diffuse X-ray scattering, infrared spectroscopy, resistivity, x-ray topography, and transmission electron microscopy have shown that defects in as-grown samples could be related to the B swirls. 450ºC anneals have shown the presence of vacancies in low carbon samples while high carbon concentration inhibited Thermal Donor (TD) formation. Our results confirm models by Newman and Mathiot for thermal donors generation. For 650ºC anneals carbon promotes New Donors (ND) formation. Our results show that these defects are mainly vacancy in nature and agrees with the substitutional oxygen models proposed for these donors. Donor formation was observed at 550ºC which could be related to New Thermal Donors (NTD) proposed by Kamiura et al..

Strukturální změny, strukturální nezaměstnanost a její řešení na karvinském trhu práce / Structural changes, structural unemployment and its solution on the labor market in the region Karvinsko

Kuželová, Kateřina January 2010 (has links)
This thesis is concentrated on the labor market in the past five years in region Karvinsko. The aim of thesis is to explore the ways in which is solved the imbalance of labor market in this region and to analyze effectiveness of spending money on active employment policy. The deman and supply sides of the labour market are detailly invastigated due to their great influence on the economic development. The thesis deals the efficiency of active employment policy in region Karvinsko, especially community services, retraining and socially useful jobs. Other part of my thesis is evaluation of the case study among the unemployed who are in evidence of the Job centre in Karvina.

Analýza zadluženosti podnikové sféry dle jednotlivých odvětví v letech 2011-2015 / Analysis of debt financing by individual sectors for the period from 2011 to 2015

Bělinová, Kristýna January 2016 (has links)
The main goal of this thesis is to find out whether is within individual industries preferred as the main source of financing debt financing for the period from 2011 to 2015. Then determine an industry that prefers foreign capital the most and select three representatives from that industry and analyze them in detail. Materials that are used for this work have the character of available public resources. The thesis is divided into three main parts. The theoretical part explains the indicators of the debt, theories to determine the optimal debt and other terms that are used in the third part. In the second part are described individual industries using the classification CZ NACE. Work is finished by the summary, which sums the findings

Využití IT nástrojů při organizaci ESN CZ National Platform / Usage of IT tools while organizing ESN CZ National Platform

Sládková, Pavlína January 2011 (has links)
Student organisations offer many opportunities to try out numbers of real projects with real budgets and deadlines. However, the high turnover of members in these organizations and imperfect knowledge transfer between the generations slow down the improvements and realization of different projects. This diploma thesis describes planning, preparation, implementation and evaluation of a specific project within the Erasmus Student Network Czech Republic (ESN CZ) which aims to meet representatives of all student organizations involved in ESN CZ. Through the description of the event, introduction to project management and their interconnection reader gets a comprehensive view on the issue of organizing the ESN CZ National Platform (ESN CZ NP). A following review of the IT tools available on the market, their evaluation and selection of a few specific applications offer options in IT project management support. Selected IT tools are demonstrated in real situations, including the recommendation for other useful functionalities. The diploma thesis is dedicated to project management from the perspective of a student organization dealing with the preparation of specific event in the context of the general phases of project management, creating manual for future coordinators ESN CZ NP.

Jánková, Vendula January 2014 (has links)
The aim of this thesis is to analyze the economic effects of the VAT rate changes to the czech households. Under investigation are three VAT rate regimes including the standard VAT rate and the reduced VAT rate of 21% and 15%, the uniform VAT rate of 17,5% and the standard VAT rate and two reduced VAT rates of 21%, 15% and 10%. The first of two intermediate aims of this thesis is to assign the appropriate tax rate to divisions, groups and classes of the classification CZ-COICOP at each of the evaluated VAT rate regimes. The second intermediate aim is to evaluate impacts of different tax burden caused by different VAT rate regime to the czech households devided into deciles by their income.

Využití informací poskytovaných databází FADN CZ pro řízení zemědělských podniků

Žáková, Aneta January 2017 (has links)
Žáková, A. Use of information provided by database FADN CZ for the management of agricultural holdings. Diploma thesis. Brno: Mendel University in Brno, 2017. The diploma thesis deals with the use of information provided by the Farm Accountancy Data Network (FADN) for the management of agricultural holdings. It aims to propose a possible use of the FADN CZ, which contains much detailed information on agricultural holdings in the Czech Republic. In the diploma thesis is used descriptive and analytical method and method of comparison. The literature review is focused on agriculture, its position in the Czech Republic and a description of the Common Agricultural Policy and Economic Accounts for Agriculture. Subsequently is described the Farm Accountancy Data Network in detail and the possibility of its use. In the practical part there is proposed use of information obtained from the FADN CZ for benchmarking. First of all, the pyramid system of indicators is created. Benchmarks for individual indicators are determined on the basis of the information from the database of the FADN CZ. The proposed methodology is subsequently verified on the selected agricultural holding. Finally, there are proposed recommendations for the Farm Accountancy Data Network and for the farms that use it or plan to use it.
