Description
Carbon Nanotubes are one-dimensional structures with diameters ranging
between 2 and 100 nm and lengths up to hundreds of microns. They are
characterized by a large variety of peculiar characteristics such as a
semiconductive or metallic behaviour, a ballistic electrical conductivity and
enhanced field emission capabilities. Among these characteristics their
sensitivity to the radiation is very peculiar depending from their diameter
and chirality. The energy gap varies from 0.4 to 6 eV leading to a sensitivity
to the electromagnetic radiation, potentially from UV to IR. This opens the
possibility to build a wide sensitive range radiation detector for space
researches and environmental controls. Main characteristics of Carbon
Nanotubes allowing the detection of radiation will be reported together with
first results obtained exposing first prototypes to UV, visible and IR radiation.
