Welcome to Nanomaterials Laboratory at SDSM&T!

Our current research focuses on fabrication and syntheses of novel nano materials for optoelectronic devices including photovoltaics, light emitting diodes (LEDs) and lasers. Both epitaxial and colloidal nano materials are produced in the laboratory. Current focus of epitaxial nanostructures is quantum wires; colloidal examples are metallic and semiconducting nano particles. Epitaxial nano materials are fabricated by using a commercial molecular beam epitaxy (MBE) machine while nano particles are synthesized by applications of high power laser pulses on materials immersed in liquid. The electronic energy structure of these materials are characterized by photoluminescence (PL) while their morphological structures are studied by scanning probe microscopes (SPM) and transmission electron microscopy (TEM).
