Biotechnology Applied Nanostructures

WE PROPOSE TO APPLY A BIOTECHNOLOGY-BASED PROCESS TO MAKE NANOSTRUCTURES FOR OPTOELECTRONIC APPLICATIONS. THE RESULT WILL BE A UNIFORM ARRAY OF SILICON QUANTUM BOXES OF IDENTICAL DIMENSIONS IN A SILICON LAYER OF CONTROLLED THICKNESS. ALL THREE TECHNIQUES, CONTROLLED THICKNESS OF A CRYSTALLINE Si LAYER, FORMATION OF A UNIFORM ARRAY, AND ITS USE AS A PATTERN FOR REPLICATING A SEMICONDUCTOR ARRAY, HAVE BEEN DEMONSTRATED EXPERIMENTALLY. WE PROPOSE TO COMBINE AND ADAPT THESE TECHNIQUES TO GENERATE A UNIFORM ARRAY OF IDENTICAL Si QUANTUM BOXES. THEIR PROPERTIES WILL BE CHARACTERIZED BY VARIOUS ANALYTICAL TECHNIQUES INCLUDING PHOTOLUMINESCENCE SPECTROSCOPY.
