An approach for quantum capacitance of graphene, carbon nanotube, silicene and hexagonal boron nitride nanoscale supercapacitors by non-equilibrium Green's function method Özdoğan, Cem; Kökten, Hatice (2022-01-01) We introduce a comprehensive approach to calculate quantum capacitance of nanoscale capacitors as a function of applied potential difference to have resemblance to actual device operating conditions. Ab initio analysis bas...
X-Doped (X = C, N, F, P) ZnO Sheet: Density Functional Theory Calculations Kökten, Hatice (2015-03-01) The structural and electronic properties of honeycomb-like zinc oxide sheet has been investigated by performing density functional theory calculations. Carbon, Nitrogen, Fluorine and Phosphorus atom doped form of ZnO sheet...
Energetics and structural properties of carbon and oxygen doped hexagonal boron nitride sheets Kökten, Hatice (Elsevier BV, 2011-10-01) Energetics and structural properties of carbon and oxygen doped hexagonal boron nitride sheets have been investigated by performing density functional theory calculations. Substitutional doping model has been considered in...
Oxygen-doped c-BN(110) surface: DFT calculations Kökten, Hatice (2010-07-16) Density functional theory calculations have been performed to investigate the structural and electronic properties for both unrelaxed and relaxed cases of oxygen-doped c-BN(110) surface. Oxygen atom has been substituted in...
Structural and electronic properties of carbon-doped c-BN(110) surface Kökten, Hatice (Elsevier BV, 2009-12-15) The structural and electronic properties of a substitutional C atom in a neutral charge state on both the B and N site of the c-BN(110) surface have been investigated from a theoretical point of view using density function...
Structural, Electronic and Magnetic Properties of BN Nanotubes Doped with Mn and Cr: Exploring the Potential for Device Technology Kökten, Hatice; ERKOÇ, ŞAKİR (American Scientific Publishers, 2009-04-01) Spintronics has become an increasingly important topic in device applications in the nanoscale. Several candidate systems have been studied both experimentally and theoretically in literature. In this work, we investigate ...
Structural and electronic properties of c-BN(110) surface and surface point defects Kökten, Hatice (World Scientific Pub Co Pte Lt, 2006-06-01) The surface structure, surface energy, and surface vacancy formation energy for B and N vacancy of the cubic boron nitride (c-BN)(110) surface have been investigated by performing Hartree-Fock and DFT calculations. Results...
Thermodynamics of small platinum clusters Sebetci, A; Guvenc, ZB; Kökten, Hatice (Elsevier BV, 2006-03-01) Using the Voter and Chen version of an embedded atom model, derived by fitting simultaneously to experimental data of both the diatomic molecule and bulk platinum, we have studied the melting behavior of free, small platin...
On the structural and energetic features of small metal clusters: Ni-n, Cu-n, Pd-n, Pt-n, and Pb-n; n=3-13 El-Bayyari, Z; Oymak, H; Kökten, Hatice (World Scientific Pub Co Pte Lt, 2004-07-01) Using an empirical potential energy function parametrized for each of the Ni, Cu, Pd, Pt, and Pb systems, minimum-energy structures of Ni, Cu-n, Pd-n, Pt-n, and Pb-n (n = 3-13) microclusters have been determined by perform...
