Near-Field Optical Imaging of Electromigration Damages in Passivated Metal Stripes
Electromigration is one of the main failure mechanisms limiting the miniaturization of microelectronic devices. As a consequence of the high current densities in the interconnections, hillocks and voids are fo...

Variability of Circumstellar Emission from Dust Envelopes Around Carbon Stars
The main constituents of the dust, produced around late-type carbon stars, are thought to be carbon and silicon carbide (SiC), although their exact nature is not yet well established. This subject has been add...
