Liquid Flow through Defective Layered Membranes: A Phenomenological Description
Alexander Quandt, Andrii Kyrylchuk, Gotthard Seifert +1
We present a realistic phenomenological description of liquid transport through defective, layered membranes. We derive general expressions based on conventional models of laminar…
Superior Hardness and Stiffness of Diamond Nanoparticles
Alexander Quandt, Igor Popov, David Tománek
We introduce a computational approach to estimate the hardness and stiffness of diamond surfaces and nanoparticles by studying their elastic response to atomic nanoindentation. Res…
Localization of metallicity and magnetic properties of graphene and of graphene nanoribbons doped with boron clusters
Cem Ozdogan, Jens Kunstmann, Alexander Quandt
As a possible way of modifying the intrinsic properties of graphene we study the doping of graphene by embedded boron clusters with density functional theory. Cluster doping is tec…
Stability of edge states and edge magnetism in graphene nanoribbons
Jens Kunstmann, Cem Özdoğan, Alexander Quandt +1
We critically discuss the stability of edge states and edge magnetism in zigzag edge graphene nanoribbons (ZGNRs). We point out that magnetic edge states might not exist in real sy…
Functionalizing graphene by embedded boron clusters
A. Quandt, C. Ozdogan, J. Kunstmann +1
We present a model system that might serve as a blueprint for the controlled layout of graphene based nanodevices. The systems consists of chains of B7 clusters implanted in a grap…
Broad boron sheets and boron nanotubes: An ab initio study of structural, electronic, and mechanical properties
Jens Kunstmann, Alexander Quandt
Based on a numerical ab initio study, we discuss a structure model for a broad boron sheet, which is the analog of a single graphite sheet, and the precursor of boron nanotubes. Th…
