Analysis of recent publications revealed an increasing interest in epitaxial growth of InSe/GaSe superlattice. Within the effective mass theory we carried out self-consistent calculations of the confined and itinerant electronic states, potential profile and charge density distribution of InSe/GaSe superlattice, where the InSe layers are the well and the GaSe layers the barrier. Calculations were performed for three types of doping: uniform, modulated in the well, and modulated in the barrier. It has been found that the Coulomb interaction in the well and barrier forces the formation of localized states in the barrier region. The possibility of an insulator-metal transition in InSe/GaSe superlattice is predicted for modulation doping in the barrier and for a doping level n = 10(19) cm-3. A decrease of the barrier height has been found for modulation doping in the well.

Information and communıcation technologies in Turkey and other OECD member countries Erdil, Erkan (2012-01-01) This paper investigates the economic effects of the ICT revolution. In this regard, economic impacts of ICT are evaluated by touching various segments of social and economic spheres that are deeply affected by the ICT revolution. Further, we present summary of a comprehensive survey of previous studies in the literature on the relationship between economic growth and ICT. Then, we examine the ICT sector in OECD area in general and specifically in Turkey. Depending on the results of all these attempts, we pr...
Framing mega regional trade agreements within global capitalism: an analysis of the TPP, TTIP and TISA proposals/ Kahya, Pınar; Yalman, Osman Galip; Department of Political Science and Public Administration (2016) The thesis investigates the reasons behind the emergence of a new generation of mega trade liberalization agreements in different scales. These scales are the US-the EU scale which is concretized with Transatlantic Trade and Investment Partnership (TTIP), Asia-Pacific scale which is on scope of Transpacific Partnership (TPP), and Trade in Services Agreement (TISA) which is negotiated beyond these scales. The aim of the study is to identify the main structural factors, strategies and agencies which drive the...
Macroeconomic Effects of Information and Communication Technologies in Turkey and Other OECD Member Countries Karagöl, Burak; Erdil, Erkan (Science And Technology Policies Research Center, Middle East Technical University (Ankara, Turkey), 2012) This paper investigates the effects of ICT on economic growth in Turkey and other OECD member countries. After discussing the theoretical relationships between ICT usage and economic growth, we test the positive impact of ICT revolution on economic growth econometrically. In the empirical part of the study, we perform panel data analyses by employing data sets that belong to 30 OECD member countries for 1999-2008 period as well as carrying out time series analyses for only Turkey by using data between 1980 ...
Real Exchange Rates and Growth: Contractionary Depreciations or Appreciations? Özmen, Erdal; YOLCU KARADAM, DUYGU (2021-01-01) This study investigates the impact of real exchange rates (RER) on growth of a large number of advanced (AE) and developing economies (DE) estimating conventional growth models augmented with global financial conditions variables. First of all, replicating Rodrik (2008) and following studies employing panel autoregressive distributed lag (PARDL) and PARDL mean group (PARDL-MG) models, we show that the expansionary depreciation findings for DE are often based on a misinterpretation of an error correction mec...
Pluralism in science Bakdur, Eser; Sol, Ayhan; Department of Philosophy (2009) This thesis investigates the determinants of financial development in Turkey. Principle Component Analysis (PCA) is employed in order to examine the main determinants of financial sector development and shed light on the structure of the financial system in Turkey. The empirical studies on financial development suffer from the measurement problem. This study aims to remedy the measurement problem by providing proxies that explain different aspects of financial development more accurately than other proxies ...
