Semiconductor Nanowires and their field effect devices

Obiettivo

Nanowires are filamentary crystals with a very high ratio of length to diameter, the latter being in the nanometre range. From a fundamental point of view, semiconductor nanowires are of significant interest because they exhibit new physical and chemical properties owing to their large surface-to-volume ratio, low dimensionality and confinement in one dimension.
From a technological perspective, they constitute attractive building blocks for the assembly of novel nano-electronic and nano-photonic systems, a s well as biochemical sensors.
This proposal combines three complementary aspects of semiconductor nanowires: synthesis, characterization of their structural, optical and electronic properties, and application to field effect devices. All three aspects w ill run semi-simultaneously in and inter-related way.
The synthesis oriented part of the project will concern the study of the growth mechanisms of nanowires, the synthesis with alternative catalysts and the understanding of the synthesis of new crystallin e structures.
In parallel with the synthesis studies, the optical and electronic properties of the nanowires at low temperatures will be fully characterized. In order to deterministically dispose the nanowires on a substrate, for the adequate electrical characterization, the fabrication of horizontal porous alumina as templates for nanowires will also be studied. Finally, the initial results and methodologies will be combined to the realization of field effect devices, both electrically and chemically gated.
