Hydrogen-induced disintegration of fullerenes and nanotubes: An ab initio study
Savas Berber, David Tomanek
We use ab initio density functional calculations to study hydrogen-induced disintegration of single- and multi-wall carbon fullerenes and nanotubes. Our results indicate that hydro…
Comparison of Wide and Compact Fourth Order Formulations of the Navier-Stokes Equations
Ercan Erturk
In this study the numerical performances of wide and compact fourth order formulation of the steady 2-D incompressible Navier-Stokes equations will be investigated and compared wit…
Revealing Sub-Surface Vibrational Modes by Atom-Resolved Damping Force Spectroscopy
Makoto Ashino, Roland Wiesendanger, Andrei N. Khlobystov +2
We propose to use the damping signal of an oscillating cantilever in dynamic atomic force microscopy as a noninvasive tool to study the vibrational structure of the substrate. We p…
Ab-initio design of half-metallic fully-compensated ferrimagnets: the case of CrMnZ (Z= P, As, Sb, Bi) compounds
I. Galanakis, K. Ozdogan, E. Sasioglu +1
Electronic structure calculations from first-principles are employed to design some new half-metallic fully-compensated ferrimagnets (or as they are widely known half-metallic anti…
Defects in CrAs and related compounds: a route to half-metallic ferrimagnetism
I. Galanakis, K. Ozdogan, E. Sasioglu +1
Half-metallic ferrimagnetism is crucial for spintronic applications with respect to ferromagnets due to the lower stray fields created by these materials. Studying the effect of de…
Effect of doping and disorder on the half-metallicity of full Heusler alloy
I. Galanakis, K. Ozdogan, E. Sasioglu +1
Heusler alloys containing Co and Mn are amongst the most heavily studied half-metallic ferromagnets for future applications in spintronics. Using state-of-the-art electronic struct…
