Quantum Statistics and Structural Topology Govern Thermal Transport in Two-Dimensional Monolayer Amorphous Carbon
Gizem Kurt, Haldun Sevincli
We investigate the quantum thermal conductivity (TC) of two-dimensional monolayer amorphous carbon (MAC). We employ three distinct amorphization algorithms to generate various poss…
Quartic energy band engineering in artificial semiconductor honeycomb lattices
Emre Okcu, Emre Mesudiyeli, Hâldun Sevinçli +1
Artificially engineered lattices provide a flexible platform for reproducing and extending the electronic behavior of atomic-scale materials. Artificial graphene systems, in partic…
Anomalous diffusion in multichannel systems without a Lévy distribution of disorder
Hazan Ozkan, Stephan Roche, Haldun Sevincli
We show that multichannel quantum systems with uncorrelated but asymmetric Anderson-type disorder can exhibit anomalous diffusion, even in the absence of heavy-tailed disorder. Usi…
Collapse of the vacuum in hexagonal graphene quantum dots: a comparative study between the tight-binding and the mean-field Hubbard models
Mustafa Polat, Hâldun Sevinçli, A. D. Güçlü
In this paper, we perform a systematic study on the electronic, magnetic, and transport properties of the hexagonal graphene quantum dots (GQDs) with armchair edges in the presence…
Directed Growth of Hydrogen Lines on Graphene: High Throughput Simulations Powered by Evolutionary Algorithm
G. Ozbal, J. T. Falkenberg, M. Brandbyge +2
We set up an evolutionary algorithm combined with density functional tight-binding (DFTB) calculations to investigate hydrogen adsorption on flat graphene and graphene monolayers c…
Tuning thermal transport in graphene via combinations of molecular antiresonances
Koray Sevim, Hâldun Sevinçli
We propose a method to engineer the phonon thermal transport properties of low dimensional systems. The method relies on introducing a predetermined combination of molecular adsorb…
