Fabrication of Gallium Indium Arsenide Phosphide Quantum Wire Heterostructures for Optoelectronic Applications

85 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 1997.Thermal annealing techniques were also applied to QWRs. After this treatment, emissions were found to be at a higher energy than the as-grown samples, attributed to the disordering of the lateral composition modulation which, in effect, raised the bandgap energy of the QWR material. In addition, annealing was also found to reduce the magnitude but maintain the direction of a red-shift in emission wavelength with cooling measurement temperature. This thermal treatment served to be a useful tool in engineering the emission wavelength from a QWR sample from 1.6 to 1.55 mm.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
