Ballistic thermoelectric properties of monolayer semiconducting transition metal dichalcogenides and oxides
Özbal, Gözde; Senger, Ramazan Tuğrul; Sevik, Cem; Sevinçli, Haldun (American Physical Society, 2019-08)Combining first-principles calculations with Landauer-Mittiker formalism, ballistic thermoelectric transport properties of semiconducting two-dimensional transition metal dichalcogenides (TMDs) and oxides (TMOs) (namely ... -
Directed growth of hydrogen lines on graphene: High-throughput simulations powered by evolutionary algorithm
Özbal, Gözde; Falkenberg, J. T.; Brandbyge, M.; Senger, Ramazan Tuğrul; Sevinçli, Haldun (American Physical Society, 2018-07)We set up an evolutionary algorithm combined with density functional tight-binding calculations to investigate hydrogen adsorption on flat graphene and graphene monolayers curved over substrate steps. During the evolution, ... -
Fröhlich polaron calculations in non-integer dimensional space as a model of confinement
Özbal, Gözde (Izmir Institute of Technology, 2013)Polaron is a quasiparticle describing an electron in interaction with phonons of a medium. A microscopic description of large polaron is given by the Fr¨ohlich Hamiltonian which does not admit exact solutions. For calculating ... -
Structural, vibrational, and electronic properties of single-layer hexagonal crystals of group IV and v elements
Özdamar, Burak; Özbal, Gözde; Çınar, Mustafa Neşet; Sevim, Koray; Kurt, Gizem; Kaya, Birnur; Sevinçli, Haldun (American Physical Society, 2018-07)Using first-principles density functional theory calculations, we investigate a family of stable two-dimensional crystals with chemical formula A2B2, where A and B belong to groups IV and V, respectively (A=C, Si, Ge, Sn, ...
