Melting and freezing have been one of the most fascinating phenomena in daily life. Abrupt changes occur in the properties of a substance when it is heated through its melting point. Such phase…
Adsorption of H 2 O , N H 3 , CO, N O 2 , and NO on graphene: A first-principles study
- O. Leenaerts, B. Partoens, F. Peeters
- Materials Science, Chemistry
- 9 October 2007
Motivated by the recent realization of graphene sensors to detect individual gas molecules, we investigate the adsorption of ${\mathrm{H}}_{2}\mathrm{O}$, $\mathrm{N}{\mathrm{H}}_{3}$, CO,…
From graphene to graphite : Electronic structure around the K point
- B. Partoens, F. Peeters
- Physics
- 2 August 2006
Within a tight-binding approach we investigate how the electronic structure evolves from a single graphene layer into bulk graphite by computing the band structure of one, two, and three layers of…
NANOINDENTATION OF A CIRCULAR SHEET OF BILAYER GRAPHENE
- M. Neek-Amal, F. Peeters
- Physics
- 11 June 2010
Nanoindentation of bilayer graphene is studied using molecular dynamics simulations. We compared our simulation results with those from elasticity theory as based on the nonlinear Foppl- Hencky…
Anomalous Raman spectra and thickness-dependent electronic properties of WSe2
- H. Sahin, S. Tongay, F. Peeters
- Physics, Chemistry
- 23 March 2013
Typical Raman spectra of transition metal dichalcogenides (TMDs) display two prominent peaks, E2g and A1g, that are well separated from each other. We find that these modes are degenerate in bulk…
Realization of a tunable artificial atom at a supercritically charged vacancy in graphene
- J. Mao, Yuhang Jiang, E. Andrei
- Physics
- 31 August 2015
Single carbon vacancies in graphene can host a positive charge that is tunable. When this charge is large enough such vacancies resemble artificial atoms, with an induced sequence of quasi-bound…
Snake orbits and related magnetic edge states
- J. Reijniers, F. Peeters
- Physics
- 24 February 2000
We study the electron motion near magnetic field steps at which the strength and/or sign of the magnetic field changes. The energy spectrum for such systems is found and the electron states (bound…
Mechanical properties of monolayer GaS and GaSe crystals
- M. Yagmurcukardes, R. T. Senger, F. Peeters, H. Sahin
- Materials Science, Physics
- 5 December 2016
The mechanical properties of monolayer GaS and GaSe crystals are investigated in terms of their elastic constants: in-plane stiffness (C), Poisson ratio $(\ensuremath{\nu})$, and ultimate strength…
Quasibound states of quantum dots in single and bilayer graphene
- A. Matulis, F. Peeters
- Physics
- 28 November 2007
Dirac fermions interacting with a cylindrically symmetric quantum dot potential created in single and bilayer graphene are not confined but form quasibound states. The broadening of these quasibound…
Plasmonic excitations in Coulomb-coupled N-layer graphene structures
- J.J. Zhu, S. M. Badalyan, F. Peeters
- Physics
- 9 December 2012
We study Dirac plasmons and their damping in spatially separated N-layer graphene structures at finite doping…
