We extend our previous shell effect observation in gold nanowires at room temperature
under ultrahigh vacuum to the other two noble metals: silver and copper. Similar to gold …

The conductivity tensor is introduced for the low-dimensional electron systems. Within the
particle-in-a-box model and the diagonal response approximation, components of the …

We present a method for density-functional modeling of metallic overlayers grown on a
support. It offers a useful tool to study nanostructures, combining the power of self-consistent …

The formation of gold nanowires in vacuum at room temperature reveals a periodic spectrum
of exceptionally stable diameters. This is identified as shell structure similar to that which …

We report experiments on aluminium nanowires in ultra-high vacuum at room temperature
that reveal a periodic spectrum of exceptionally stable structures. Two'magic'series of stable …

Electromigration in interconnects continues to be an important field of study in integrated
circuits as the interconnects are planned to shrink in size at comparable pace as the …

Experimental conductance histograms for Na nanowires are analyzed in detail and
compared to recent theoretical results on the stability of cylindrical and elliptical nanowires …

We investigate the elongation and breaking process of metallic nanowires using the ultimate
jellium model in self-consistent density-functional calculations of the electronic structure. In …

Geometric effects influencing scanning tunnelling microscopy (STM) image formation of
single wall carbon nanotubes (SWCNTs) were studied within the framework of a simple …

We present an experimental and theoretical study of the conductance and stability of Mg
atomic-sized contacts. Using mechanically controllable break junctions (MCBJ), we …
