The thesis describes novel semiconductor quantum wire infrared photodetectors in the long- and very long-wavelength regions. The infrared photodetectors are based on intersubband transitions in semiconductor quantum wires and have the potential for higher operational temperature, increased signal-to-noise ratio, reduced dark current, wider spectral range and sensitivity to normal incident radiation. The quantum wire IR detectors were implemented using a nonlithographic nanostructure fabrication technique that is capable of producing large arrays of semiconductor quantum wires of a variety of materials and on different substrates. The operational principles, design procedure as well as the implementation of the quantum wire photodetectors using electrochemical anodization will be described.
