  Silicon nanowires are potentially transformative photovoltaic materials. Nanowire arrays are commonly synthesized using metal seeds. The growth process often introduces metal impurities into wires which degrade their electronic properties. We have used a plasma-assisted, vapor-liquid-solid process to grow silicon nanowires using tin seeds.  The tin is etched by the hydrogen plasma while the wires grow, resulting in self terminating wires which are metal free. 

  Stitching defects make the film weaker, but have no electronic effect

Supermolecular, helical assemblies are a common structural motif exploited in far-ranging biological contexts, from the flagellar appendages of swimming microorganisms to the protein coats that sheath rod-like viruses.  The screw-like structure of these

The LCMRCconducts collaborative research with Cal Poly Pomona, a Hispanic Serving Institution. Cal Poly Chemistry Juniors work in the Department’s research laboratory for two quarters during the AY, then continue their research full time at the LCMRC labs in Boulder during the summer. Cal Poly students are able able to take advantage of the dynamic atmosphere and interdisciplinary expertise of the LCMRC and use

Connections between “quantum dots” may enable new types of solar cells
