With transistors set to reach their smallest possible size in the next decade, the silicon chip is likely to change dramatically, or be replaced entirely. The transistor industry's path which has been largely shaped by Gordon Moore's famous prediction that ...
A cw-244-nm-Ar+-laser was used to fabricate Bragg gratings in pristine Bi-Al-SiO2 optical fibers with index changes as high as 3.6 x 10E-4. Thermal annealing revealed peaks in the energy distribution at 1.2 and 2.3 eV. ...
We demonstrate an efficient numerical scheme for the computation of the excitonic optical response of actual GaAs/AlGaAs quantum wire structures including a large set of relevant effects; structural, valence band-mixing, dielectric and many-body effects ca ...

We show that thin sheets under boundary confinement spontaneously generate a universal self-similar hierarchy of wrinkles. From simple geometry arguments and energy scalings, we develop a formalism based on wrinklons, the localized transition zone in the m ...
In this thesis, the electronic structures of low-dimensional carbon allotropes have been studied. In particular, the spatially-resolved photocurrent responses of devices comprising carbon nanostructures were investigated through scanning photocurrent micro ...
We propose in this paper a novel method for generating the pump and probe signals for a Brillouin fibre sensor. It is based on the injection locking of two distinct semiconductor lasers, that makes possible the generation of high purity beat signals in the ...
We use scanning tunneling spectroscopy (STS) at low temperatures to investigate the local electronic structure of mono- and bilayer graphene grown epitaxially on SiC(0001). Already for monolayer graphene, a gap opening is observed in the pi-bands at the Di ...
We combine optical microspectroscopy and electronic measurements to study how gold deposition affects the physical properties of graphene. We find that the electronic structure, the electron-phonon coupling, and the doping level in gold-plated graphene are ...
