Ordered Layers of Co Clusters on BN Template Layers

Ordered mono- and multi-layers from

This thesis reports on the investigation of self-assembled monoand multilayers from nanographene derivatives via scanning tunneling microscopy (STM) at solid-liquid interfaces. Because of the unique electronic properties associated with their π-bonded topology, nanographenes are promising building blocks for molecular and organic electronics, which provide the possibility of tunability together...

Ordered equilibrium structures of soft particles in thin layers.

Considering a system of gaussian particles confined between two hard, parallel plates, we investigate at T = 0, ordered equilibrium configurations that the system forms as the distance D between the plates gradually increases. Using a very sensitive and reliable optimization technique that is based on ideas of genetic algorithms, we are able to identify the emerging sequences of the energetical...

Optical properties of ordered mesoporous layers of silica

Mesoporous layers of silica are of interest for many optical applications, including the creation of devices ranging from optical sensors to laser sources with promising characteristics. Their optical characterization goes through the interpretation of measurements. We propose to give experimental results of reflectance and scattering measurements concerning mesoporous layers of silica deposite...

Highly ordered ultralong magnetic nanowires wrapped in stacked graphene layers

We report on the synthesis and magnetic characterization of ultralong (1 cm) arrays of highly ordered coaxial nanowires with nickel cores and graphene stacking shells (also known as metal-filled carbon nanotubes). Carbon-containing nickel nanowires are first grown on a nanograted surface by magnetron sputtering. Then, a post-annealing treatment favors the metal-catalyzed crystallization of carb...
