The formation of epitaxially stabilized nickel and cobalt silicides by pulsed laser annealing
… of epitaxially stabilised nickel and cobalt silicides by pulsed laser annealing has been investigated. Thermally grown NiSi and CoSi and Si<111> substrate were irradiated with laser pulses in the energy density range between 0.4 - 1.0 J/cm² in an attempt to produce epitaxially stabilized …

Indium growth and island height control on Si submonolayer phases
<p>The quantum size effects (QSE) make it possible to control the dimensions of self-assembled nanostructures. An important goal in present day surface science is to grow uniform sized self-assembled nanostructures. One system which has displayed a number of interesting surface structures is Pb/In …

Growth and characterisation of group-III nitride-based nanowires for devices
One of the main goals of this thesis was to get more insight into the mechanisms driving the growth of nitride nanowires by plasma-assisted molecular beam epitaxy (PA-MBE). The influence of the group-III and group-V flux as well as the substrate temperature Tsub has been studied leading to the …
