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…
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…
Reversible switching of surface texture by hydrogen intercalation
T. Brugger, H. Ma, M. Iannuzzi +5
The interaction of atomic hydrogen with a single layer of hexagonal boron nitride on rhodium leads to a removal of the h-BN surface corrugation. The process is reversible as the hy…
Boron Nitride Nanomesh: A template for Nano-ice
Haifeng Ma, Thomas Brugger, Simon Berner +5
Using variable temperature scanning tunneling microscopy and dI/dz barrier height spectroscopy, the structure of water on h-BN/Rh(111) nanomesh has been investigated. Below its des…
