     Chemistry of 

     Nanoscale Semiconductors 
  
 
 
 

OVERVIEW
Research in the Coffer Group is broadly focused on multi-functional semiconducting nanostructures relevant to health and energy. In both classes, the ability to manipulate surface chemistry is a key component of the science we do.

Nanoscale Silicon-Based Materials for Health. Current classes include:  Silicon nanotubes (SiNTs), porous silicon particles (pSi), and associated composites with biocompatible polymers for tissue engineering and drug delivery.

 

New Nanoscale Silicon Materials for Energy Applications We are currently taking advantage of some of the preparative routes described above for silicon nanotubes, along with new porous silicon structures, for the purpose of harvesting novel platforms relevant to photovoltaics as well as energy storage (batteries).

 

A major effort that exploits the porous matrix as a template for a class of photovoltaic / optoelectronic materials known as metal halide perovskites is currently underway; the associated interfacial chemistry is proving to be a major influence on the technologically-useful properties of these new materials.
