Band alignment issues in metal/dielectric stacks: a combined photoemission and inverse photoemission study of the HfO 2/Pt and HfO 2/Hf systems
Sayan, S.; Bartynski, R.A.; Robertson J.; Suehle, J. S.; Vogel, E.; Nguyen, N. V.; Ehrstein, J.; Kopanski, J. J.; Süzer, Şefik; Holl, M. B.; Garfunkel, E. (Electrochemical Society, 2004)We have studied the HfO 2/Hf and HfO 2/Pt systems by photoemission and inverse photoemission spectroscopies. It is found that the "effective workfunction" of metals in multilayer structures are different than their vacuum ... -
Band alignment issues related to HfO2/SiO2/p-Si gate stacks
Sayan, S.; Emge, T.; Garfunkel, E.; Zhao, X.; Wielunski, L.; Bartynski, R. A.; Vanderbilt, D.; Suehle, J. S.; Süzer, Şefik; Banaszak Holl, M. (American Institute of Physics, 2004-12-15)The valence and conduction band densities of states for the HfO2/SiO2/Si structure are determined by soft x-ray photoemission and inverse photoemission. First principles calculations are used to help in assigning valence ... -
Business cycles and workers' remittances; how do migrant workers respond to cyclical movements of GDP at home?
Sayan, S. (International Monetary Fund, 2006)Workers' remittances are often argued to have a tendency to move countercyclically with the GDP in recipient countries since migrant workers are expected to remit more during down cycles of economic activity back home. ... -
A comparative investigation of the price competitiveness of Turkish and Southeast Asian exports in the European Union market, 1990-1997
Kotan, Z.; Sayan, S. (Routledge, 2002)The relative concentration with respect to export markets and products makes export receipts of Turkey vulnerable to fluctuations in the demand conditions. Given that most of the Turkish exports face intense competition ... -
The contribution of the Black Sea Economic Co-operation organisation to regional development
Sayan, S. (Nomos Verlagsgesellschaft, 2002)Prior to the disintegration in the late 1980s of the Soviet bloc and then the Soviet Union itself, most of the economies in eastern Europe were members of CMEA/COMECON (the Council of Mutual Economic Assistance) that was ... -
Demographic shock transmission from large to small countries: an overlapping generations CGE analysis
Kenc, T.; Sayan, S. (Elsevier Inc., 2001)International commodity and capital flows provide channels for the transmission of the effects of demographic changes in large countries onto small open economies by altering the prices and interest rates facing them. This ... -
The effects of the BSEC on regional trade flows
Sayan, S. (Institute of International Economic Relations, 2005)The purpose of this paper is to discuss accomplishments of the BSEC in reference to conventional modes of economic integration in light of the particular circumstances underlying the organisation's formation. The discussion ... -

Guest workers' remittances and output fluctuations in host and home countries: the case of remittances from Turkish workers in Germany
Sayan, S. (Routledge, 2004)Over the past decades, different Mediterranean countries have sent considerable numbers of workers to the EU area, generating sizable amounts of foreign exchange receipts through the remittances these guest workers have ... -
H-O for H2O: can the Heckscher-Ohlin framework explain the role of free trade in distributing scarce water resources around the Middle East?
Sayan, S. (Walter de Gruyter GmbH, 2003)This paper aims to test econometrically the validity of Heckscher–Ohlin (H–O) theory within the context of export patterns of 11 relatively waterabundant and relatively water-scarce countries located in the Eastern ... -
Heckscher-Ohlin revisited: implications of differential population dynamics for trade within an overlapping generations framework
Sayan, S. (Elsevier BV, 2005)This paper investigates the implications of the addition of differential population dynamics to a simple 2 × 2 × 2 model of international trade within an overlapping generations framework. The two regions considered are ... -
Identification of parametric policy options for rehabilitating a pay-as-you-go based pension system: an optimization analysis for Turkey
Sayan, S.; Kiraci, A. (Routledge, 2001)Publicly managed pension systems operating on the basis of pay-as-you-go (PAYG) schemes face financial difficulties worldwide. The expenditure-revenue balances of such a system are determined jointly by the selected ... -
Measuring the degree of block interdependence between agricultural and non-agricultural sectors in Turkey
Sayan, S.; Demir, N. (Routledge, 1998)Based on the similarity of productive activities carried out by sectors, national input-output (IO) matrices may be divided into sub-matrices each representing a broader group of sectors called blocks. The strength of ... -
Methyldecalin hydrocracking over palladium/zeolite-X
Sayan, S.; Demirel, B.; Paul, J. (Elsevier Science Ltd, Exeter, United Kingdom, 2000)Hydrocracking of methyldecalin over Pd/REX has been studied with surface sensitive techniques in the critical temperature range 325– 3508C. Results from in situ characterization of adsorbed species, and post-reaction ... -
On the mechanism of CO adsorption on a silica-supported ruthenium catalyst
Kantcheva, M.; Sayan, S. (1999)The adsorption of CO at room temperature on a Ru/SiO2 catalyst has been studied by means of FTIR spectroscopy. Spectral evidence for formation of water molecules and a quantity of very dispersed ruthenium on the catalyst ... -
Parametric pension reform with higher retirement ages: a computational investigation of alternatives for a pay-as-you-go-based pension system
Sayan, S.; Kiraci, A. (Elsevier BV, 2001)This. paper discusses parametric reform options to control losses generated by a publicly managed pay-as-you-go (PAYG) pension system under alternative deficit reduction (reform) strategies involving changes in contribution ... -

Simulation of benefits and risks after the planned privatization of the pension system in Turkey
Teksoz, A. T.; Sayan, S. (Routledge, 2002)The recently started process of social security reform in Turkey is widely argued to have a significant potential to affect the direction of further development of financial markets in the country in the years ahead, ... -
Soft x-ray photoemission studies of Hf oxidation
Süzer, Şefik; Sayan, S.; Banaszak Holl, M. M.; Garfunkel, E.; Hussain, Z.; Hamdan, N. M. (A I P Publishing LLC, 2003)Charging of oxide films under x rays is an important issue that must be taken into consideration for determination of core-level binding energies as well as valence band offsets. Measurements are taken as a function of ... -
Soft x-ray photoemission studies of the HfO2/SiO2/Si system
Sayan, S.; Garfunkel, E.; Süzer, Şefik (American Institute of Physics, 2002)Soft x-ray photoelectron spectroscopy with synchrotron radiation was employed to study the valence-band offsets for the HfO2/SiO 2/Si and HfO2/SiOxNy/Si systems. We obtained a valence-band offset difference of -1.05±0.1eV ...
