<P>PROBLEM TO BE SOLVED: To provide a wavelength-sensitive detector that is based on elongated nanostructures, for example, nanowires. <P>SOLUTION: The elongated nanostructures are parallel with respect to a common substrate, and they are grouped in at least first and second units of a plurality of parallel elongated nanostructures. The elongated nanostructures are positioned between a first electrode and a second electrode, while the first and second electrodes lie respectively in a first plane and a second plane substantially perpendicular to the plane of the substrate, whereby all elongated nanostructures in a same photoconductor unit are contacted by the same two electrodes. A circuitry is added to read out electrical signals from the photoconductor units. The electronic density of states of the elongated nanostructures in each unit is different because the material, of which the elongated nanostructures are made, is different, or because the diameter of the elongated nanostructures is different. Each unit of the elongated nanostructures therefore gives a different response to incident photons such that wavelength-specific information can be derived with the proposed device. <P>COPYRIGHT: (C)2007,JPO&INPIT |
