Nonlithographic semiconductor nanoscale devices

Summary form only given. We have developed a thin film template based nanostructure synthesis technique that is applicable for the development of high performance electronic and photonic devices on silicon, glass and other planar substrates. The technique is based on the anodization of a thin film of aluminum to form an alumina template;. synthesizing the active material inside these nanoscale pores then forms the nanostructures. We are currently using the above template-based technology for the fabrication of a variety of devices including (i) nanostructure-based solar cells, (ii) narrowband optical detectors, (iii) electro-optic modulators and (iv) Coulomb-blockade devices
