PANI films were deposited on glass substrates by in-situ polymerization and characterized by UV-VIS spectroscopy and atomic force microscopy. A method is developed to accurately analyze ellipsometric data obtained for transparent glass substrates before and after modification with absorbing polymer films. Surface modification was made with an overlayer such as polyaniline ( PANI), which exhibits different optical properties by varying its oxidation state. First, the issue of using transparent substrates for ellipsometry studies was examined and then, spectroscopic ellipsometry was used to characterize absorbing overlayers on transparent glasses. The same methodologies of data analysis can be also applied to other absorbing films on transparent substrates, and deposited by different techniques.

Economic crises caused by speculative bubbles are recurring in economic history but there is still no consensus on how it begins, grows and overflows. Economists and regulators seem to be inefficient in predicting and preventing this process, which is so detrimental to economic functioning. This failure proved to be obvious with the American subprime crises, which had great impact on various sectors of the U.S. economy. In this paper, we perform a literature review of the traditional theory of finance, mainly represented by the Efficient Market Hypothesis. According to this theory, asset prices always reflect their intrinsic value, assumption that doesn’t match the price boom followed by a crash, observed in the crisis generated by speculative bubbles. Finally, we present a new way to analyze this phenomenon, in the light of the investors’ behavioral aspects and the flaws inherent to the financial markets
