Materials Synthesis Facility
Contact: Charles Black
The Materials Synthesis Facility includes two laboratories devoted to producing nanostructured materials. We support capabilities
for inorganic nanomaterials synthesis of silicon-, boron-, and/or carbon-based nanomaterials by low-pressure chemical vapor deposition.
As well, the facility staff has significant experience with solution-phase chemistry methods of nanocrystal/nanowire materials.
Analytical tools for material characterization include powder x-ray diffraction, thermal measurement equipment, and an electrochemistry
workstation.
A second laboratory provides infrastructure for solution-based processing of organic thin films, including tools for spin-casting,
drip-coating, thermal processing, and UV/ozone treatment. Included in this laboratory are a plasma etch tool and inorganic thin film
deposition by thermal evaporation.
Capabilities
Inorganic Materials Synthesis
Contact: Weiqiang Han (whan@bnl.gov)
- Inorganic nanomaterials synthesis and characterization capabilities include low-pressure chemical vapor deposition (CVD), electron-beam evaporation,
electrochemical deposition, x-ay diffraction, thermal measurement equipment, and oxygen-free processing environments. Our low-pressure CVD system
(CVD Inc/ First Nano 3000) is an inductively heated low-pressure system capable of handling silicon-, boron-, and/or carbon-based depositions. The
electron-beam evaporation system (Mantis Quad-EV-C mini evaporator) is a low power four-pocket evaporator supporting material co-evaporation. An
electrochemistry workstation (Princeton Applied Research Parastat 2273-SYS Potentiostat) which is used for general electrochemistry synthesis and
measurements.
- The X-ray diffractometer (Rigaku Miniflex II) is a basic powder diffractometer for phase identification. Thermal measurement equipment, Thermogravimetry/
Differential Thermal Analyzer/ Differential Scanning Calorimetry (TG/DTA/DSC), has simultaneous DTA/TGA and DSC capabilities for analyzing reactions
and phase transitions. The glovebox (M. Braun Labmaster 130) is used for processing air and moisture sensitive materials.
Thin-Film Processing
Contact: Charles Black (ctblack@bnl.gov)
- The group supports a thin-film materials processing laboratory outside the cleanroom environment, which includes small, versatile versions of the
Nanofabrication Facility toolset. The laboratory includes facilities for organic film deposition by spin-coating and thermal processing in vacuum
or inert gas environments. A March Plasma CS1701F reactive ion etch tool supports SF6, CHF3, CF4, CF3Br,
and O2 gas chemistries. Metal film deposition by thermal evaporation and DC magnetron sputtering is supported by a
Kurt J. Lesker PVD75 tool. The laboratory includes chemical fume hoods and optical microscopes for sample processing and inspection.
Macromolecular and Nanomaterial Synthesis & Assembly
Contact: Oleg Gang (ogang@bnl.gov)
- Capabilities include techniques and methods required for the synthesis, fabrication and study of novel hybrid structures
and functionalities using regulated nanoscale assembly and self-organization approaches. Capabilities and expertise include
solution-based synthesis and characterization of a variety of soft, biological, hybrid and inorganic nanomaterials, advanced
functionalization routes for surfaces and nano-objects, and selective biomolecular recognition.
Structural Probing
Contact: Oleg Gang (ogang@bnl.gov)
- In-situ structural characterization can be performed for surfaces, thin films nanoparticles, biological complexes, nanofabricated
structures and hybrid composites under environmental condition. We utilize the range of x-ray, optical, spectroscopic and scanning
probe methods for structure characterization.
