Electrodeposition of Nanostructured Crystalline Inorganic Semiconductors for Electrochemical Energy Conversion/Storage
Stephen Maldonado, Ph.D.
University of Michigan
This presentation will highlight recent work by our research group on the synthesis, design, and study of nanostructured semiconductors as materials in (photo)electrochemical energy conversion systems. A general and brief overview/motivation for nanostructured semiconductors in energy conversion applications will first be given. The primary topic is our recent discovery of a benchtop method to produce crystalline nanostructured semiconductor films under ambient conditions with minimal energy input. Data will be presented on our electrochemical liquid-liquid-solid (ec-LLS) process for the preparation of crystalline group IV and III-V semiconductors. This process affords tunable morphologies without any physical or chemical templating agent. Results from experiments aimed at identifying the controlling features of this process will be presented.
Stephen Maldonado received his BS in chemistry from the University of Iowa in 2001 and a PhD in chemistry from the University of Texas at Austin in 2006. After two years as a postdoctoral fellow at Caltech, Dr. Maldonado joined the faculty at the University of Michigan, Ann Arbor. He is an officer in the Society of Electroanalytical Chemistry, member of the State of Michigan Green Chemistry Roundtable, and received an NSF CAREER award in 2010. His group's general research interests focus on electrochemical processes relevant to the fields of electronics and energy conversion/storage.
