Abstract
The Center for Functional Nanomaterials (CFN) at Brookhaven National
Laboratory is a science-based user facility devoted to nanotechnology
research addressing challenges in energy security. Five internal research
groups (Electronic Nanomaterials, Catalysis/Surface Science, Biology/Soft
Materials, Electron Microscopy, and Theory/Computation) accompany a broad
portfolio of scientific capabilities and an active external user program.
I will provide an overview of the CFN facilities, which are accessible at
no cost to users via a peer reviewed proposal process.
Our research program in Electronic Materials incorporates nanostructured
materials with precisely defined and tunable internal dimensions as
experimental platforms for understanding and improving electronic device
performance. We are pursuing self-assembling materials as fabrication
tools because of their ability to autonomously form patterns at
sub-lithographic feature sizes (<20nm) and pitches (<40nm), and with a
high density of features (~10^11/cm2). Although patterns formed via self
assembly typically have only limited positional order and a high density
of defects, they are nevertheless well-suited to large-area device
applications such as solar cells. I will present our research progress
implementing self-assembly approaches into nanostructured solar cell
designs, as well as our previous successful implementation of self
assembly in high-performance semiconductor devices.
Bio
Charles Black is a Scientist and the Group Leader for Electronic
Nanomaterials in the Center for Functional Nanomaterials at Brookhaven
National Laboratory. He researches applications for nanostructured
materials in photovoltaic devices. From 1996 to 2006 Dr. Black was a
Research Staff Member at the IBM Thomas J. Watson Research Center in
Yorktown Heights, New York. His research in IBM involved using self
assembly to address specific fabrication challenges in high-performance
semiconductor electronics. During his career he has at different times
performed experimental research on low-temperature scanning tunneling
microscopy, single-electron tunneling devices, superconductivity in metal
nanoparticles, nanocrystal-based electronic devices, and ferroelectric
non-volatile memories. Dr. Black earned the Ph.D. degree in Physics from
Harvard University in 1996. He has authored more than 60 scientific
publications and holds 25 US Patents.
