CFN USER PROGRAM
The Center for Functional Nanomaterials (CFN) is one of five Nanoscale Science Research Centers (NSRCs) (web), established by the U.S. Department of Energy. Through a peer-reviewed user proposal process, researchers from academic, industrial, and national laboratories can have free-of-charge access to state-of-the-art laboratory facilities and expertise for nanoscale science research (web).
EXPERTISE/FACILITIES
As a part of Electronic Nanomaterial Theme (web), we can provide experimental platforms that enable development and characterization of novel semiconducting materials and functional nanostructured devices. The main expertise and facilities are focused on nanofabrication of electronic devices and their electrical/optoelectronic/photovolatic characterization. Following are some of our experimental capabilities.
- Organic/inorganic solar cell fabrication: Bilayer, bulk heterojunction, dye-sensitized, inverted, non-inverted, conventional Si solar cells
- Field-effect transistor fabrication: Organic, inorganic nanowires
- Charge transport property characterization: Current-voltage characteristics, bulk charge mobility, field-effect transistor characteristics, 4-probe sheet resistance, temperature-dependence
- Photovoltaic/optoelectronic property characterization: Spectrally-resolved photoconductivity, photovoltaic power conversion characteristics, external quantum efficiency
- Inorganic semiconductor nanowire synthesis: Thermal chemical vapor deposition, solution-based growth
Through collaborations with other staffs in Electronic Nanomaterials Theme and National Synchrotron Light Source (NSLS), we also mediate following experimental expertise.
- Self-assembly-based nanostructuring: Anodized nanoporous metal oxide (alumina, titania), self-assembled block copolymer nanopatterning
- Nanofabrication: Large-area electron-beam lithography, nano-imprinting lithography, nano-interference lithography, reactive ion etching (metal, semiconductor, oxide), physical/chemical vapor deposition (thermal & electron beam evaporation, sputtering, atomic layer deposition)
- Synchrotron X-ray scattering: Thin film structure characterization
- Ultrafast optical spectroscopy: Pump-probe transient absorption, single-molecule spectroscopy
We are actively seeking high quality users who wish to engage in invigorating scientific interactions and breakthrough research using our research expertise and facilities. Developing productive high-impact research collaboration with users is one of our priorities. Please contact Dr. Chang-Yong Nam for more information (web)
