A measure for the chirality of triangles
Haifeng Ma, Thomas Greber
A measure for the description of the chirality of triangles is introduced. The measure is zero for triangles with at least one mirror axe, i.e. equilateral or isosceles triang…
Comment on "Potential Energy Landscape for Hot Electrons in Periodically Nanostructured Graphene"
H. G. Zhang, T. Greber
In a recent letter [Phys. Rev. Lett. 105 (2010) 036804] the unoccupied electronic states of single layers of graphene on ruthenium are investigated. Here we comment on the interpre…
Strong 3p -T1u Hybridization in Ar@C60
M. Morscher, A. Seitsonen, S. Ito +3
Multilayers of fullerenes with and without endohedral Ar units, C60 and Ar@C60, were investigated by photoemission and density functional theory. The stoichiometry and the endohedr…
Corrugated single layer templates for molecules: From h-BN Nanomesh to Graphene based Quantum dot arrays
Haifeng Ma, Mario Thomann, Jeanette Schmidlin +3
Functional nano-templates enable self-assembly of otherwise impossible arrangements of molecules. A particular class of such templates is that of sp2 hybridized single layers of he…
Laser-induced Field Emission from Tungsten Tip: Optical Control of Emission Sites and Emission Process
Hirofumi Yanagisawa, Christian Hafner, Patrick Doná +5
Field-emission patterns from a clean tungsten tip apex induced by femtosecond laser pulses have been investigated. Strongly asymmetric field-emission intensity distributions are ob…
