The presented diploma thesis deals with the preparation of perovskite single crystals by inverse thermal crystallization and subsequent study of the basic properties of these hybrid organic-inorganic materials that can be used in various optoelectronic (photodetectors, transistors, lasers, LEDs) or photovoltaic applications. Their behavior in the electric field was studied by impedance spectroscopy. Impedance and capacitance-voltage (C-V) characteristics (frequency dependences) were measured in the dark and in the light. From the impedance dependences for measurements at 0 V voltage in the dark, the equivalent circuit was modeled and its parameters and dielectric constant were determined. From the C-V dependence, Mott-Schottky analysis determined the parameters – "flat-band" potential U_"fb" and charge carrier density N_"C-V" , the parameter – the so-called Warburg coefficient was found, which together with the parameter N_"C-V" was used to calculate the diffusion coefficient D.

Local researchers demonstrate how the Cole??o Mossoroense constructs an image of Mossor?, forming in the members of the city an identity with the place, a social cohesion or creating one forms to see and to say about the Mossor? city. The Cole??o Mossoroense, through Vingt-un Rosado together with its family, established a form of seeing and identifying of the Mossor? s population with the city, just because it associated and it was, at the same time, a movement at the same time social (civic parties for example), political (the domination of the Rosado s family) and cultural (the books and theatrical parties about the city). The conjunction of the Cole??o Mossoroense as and with a social movement, cultural and political was capable to establish a social identity, a subjective constituent . With this background, it was possible to make a study of the image attributed to Dix-sept Rosado, by the Cole??o Mossoroense, through an analysis of the inherent discourse in the works by Bakhtin (1989) and Bourdieu (2000), of and on Dix-sept Rosado in the Cole??o Mossoroense based on. The image of Dix-sept Rosado was constructed by the Cole??o Mossoroense after its death, and the responsible for this was Vingt-un Rosado, which was the chief-editor of the Cole??o Mossoroense up to 2006, year of its death. The Cole??o Mossoroense built an image of Dix-sept Rosado as an enterprising man, progressive and innovator, of great capacity of leadership and oratory (a conductor of the crowds ), popular and charismatic, an honest and dynamic politician. This image made by the Cole??o Mossoroense, although when enhancing in surplus the qualities of Dix-sept Rosado have as objective to transmit an image of a heroic personage, it has some relation with the reality. Dix-sept Rosado was a man identified with its locality. This can resemble a regional nationalism. The attitudes of Dix-sept Rosado must be understood inside of a broader social context, of a time marked by the populist politics. Qualities also appreciated and developed inside of a specific historical context and determined both national and locally. The Cole??o Mossoroense enhances the qualities of Dix-sept Rosado so that the current politicians of the Rosado s family can establish a link of continuity in its contemporary political practice / Essa pesquisa compreende um estudo sobre os valores e ideais atribu?dos a Dix-sept Rosado pela Cole??o Mossoroense. Pesquisadores locais demonstram como a Cole??o Mossoroense constr?i uma imagem de Mossor?, formando nos membros da cidade uma identidade com o lugar, uma coes?o social ou criando uma forma de ver e dizer da cidade de Mossor?. A Cole??o Mossoroense, atrav?s de Vingt-un Rosado juntamente com sua fam?lia, s? conseguiu estabelecer uma forma da popula??o mossoroense de se ver e de se identificar com a cidade porque associou e foi, ao mesmo tempo, um movimento social (festas c?vicas por exemplo), pol?tico (a domina??o da fam?lia) e cultural (os livros e as pe?as teatrais sobre a cidade). A conjun??o da Cole??o Mossoroense como e com um movimento social, pol?tico e cultural foi capaz de estabelecer uma identidade social, um constituinte subjetivo . Com esse conhecimento b?sico, p?de-se partir para o estudo da imagem que a Cole??o Mossoroense atribui a Dix-sept Rosado, realizando-se uma an?lise do discurso das obras de e sobre Dix-sept Rosado na Cole??o Mossoroense fundamentado em Bakhtin (1989) e Bourdieu (2000). A imagem de Dix-Sept Rosado foi constru?da pela Cole??o Mossoroense depois de sua morte e seu respons?vel foi Vingt-un Rosado, que ficou na dire??o da Cole??o Mossoroense at? 2006, ano de seu falecimento. A Cole??o Mossoroense construiu uma imagem de Dix-sept Rosado enquanto um homem empreendedor, progressista e inovador, de grande capacidade de lideran?a e orat?ria (um condutor de multid?es ), popular e carism?tico, um pol?tico honesto e din?mico. Essa imagem constru?da pela Cole??o Mossoroense, apesar de ao real?ar em demasia as qualidades de Dix-sept Rosado tem como objetivo transmitir uma imagem de um personagem her?ico, tem alguma rela??o com a realidade. Dix-sept Rosado foi um homem identificado com a sua localidade. Isso pode ensejar um nacionalismo regional, um certo bairrismo. As atitudes de Dix-sept Rosado devem ser compreendidas dentro do contexto social mais amplo, de uma ?poca marcada pela pol?tica populista. Qualidades inclusive, apreciadas e desenvolvidas dentro de um contexto hist?rico especifico e determinado nacional e localmente. A Cole??o Mossoroense real?a as qualidades de Dix-sept Rosado para que os pol?ticos atuais da fam?lia Rosado possam estabelecer um elo de continuidade em suas pr?ticas pol?ticas contempor?neas

This work deals with modeling of progression of dielectric variables and mixture formulas for solution of properties of composite materials in dependency on frequency. Theoretical part of the work explains physical principles of polarisation mechanisms and influence on dielectric constant with changing temperature and frequency. In theoretical part processes inside the composite material, which is in electrical field are described. The work contains summary of mixture formulas and methods of their derivation. Program for use in education is a part of the work. It allows modelling of progression of dielectric variables in dependency on frequency and Cole-Cole circle diagram. In mixtures it allows modelling of frequency dependencies of dielectric constant in accordance to Maxwell's, Bőttcher's and Lichtenecker's mixture formulas.
