Band Structure and Optical Properties of Kesterite Type Compounds: First principle calculations
(Institute of Physics Publishing, 2017)In present work, our research is mainly focused on the electronic structures, optical and magnetic properties of Cu2FeSnZ4 (Z = S, Se) compounds by using ab initio calculations within the generalized gradient approximation ... -
Design of application specific processors for the cached FFT algorithm
(IEEE, 2006-05)Orthogonal frequency division multiplexing (OFDM) is a data transmission technique which is used in wired and wireless digital communication systems. In this technique, fast Fourier transformation (FFT) and inverse FFT ... -
Electron spectroscopy and the electronic structure of KNbO3: First principle calculations
(Taylor & Francis Online, 2014)The electronic structures of KNbO3were calculated within the density functional theory, and their evolution was analyzed as the crystal-field symmetry changes from cubic to rhombohedral via tetragonal phase. We carried out ... -
Electronic transport through a kink in an electron waveguide
(Institute of Electrical and Electronics Engineers, 1994)The current-voltage denendence correspondinp to electronic transport through a kink in an electronic waveguide is analyzed. No phase breaking dissipation mechanisms are considered, but the effects of the Coulomb interaction ... -
Energy dissipation in atomic force microscopy and atomic loss processes
(American Physical Society, 2001)Atomic scale dissipation is of great interest in nanomechanics and atomic manipulation. We present dissipation measurements with a linearized, ultrasmall amplitude atomic force microscope which is capable of measuring ... -
Magnetic and electric Aharonov-Bohm effects in nanostructures
(Elsevier BV, 1996)The paper reviews and extends the magnetic Aharonov-Bohm effect (persistent current, resistance oscillation) in normal-metal rings including spin-independent and spin-dependent hopping, Zeeman splitting, magnetic textures ... -
Optical properties of the narrow-band ferroelectrics: first principle calculations
(Taylor & Francis Inc., 2015)Based on density functional theory, we have studied the electronic, and optical properties of narrow-band ferroelectric compounds - (Ge,Sn) Te. Generalized gradient approximation has been used for modeling exchange-correlation ... -
The role of the interface in germanium quantum dots: when not only size matters for quantum confinement effects
(Royal Society of Chemistry, 2015)Quantum confinement (QC) typically assumes a sharp interface between a nanostructure and its environment, leading to an abrupt change in the potential for confined electrons and holes. When the interface is not ideally ... -
Theoretical and spectroscopic investigations on the structure and bonding in B-C-N thin films
(2009)In this study, we have synthesized boron, carbon, and nitrogen containing films using RF sputter deposition. We investigated the effects of deposition parameters on the chemical environment of boron, carbon, and nitrogen ... -
A Wired-AND Current-Mode Logic Circuit Technique in CMOS for Low-Voltage, High-Speed and Mixed-Signal VLSIC
(1997)A wired-AND current-mode logic (WCML) circuit technique in CMOS technology for low-voltage and high-speed VLSI circuits is proposed, and a WCML cell library is developed using standard 0.8 micron CMOS process. The proposed ...
