In addition to the cleanroom, the BNC includes a suite of specialized laboratories that provide outstanding capabilities to researchers. All BNC laboratories are designed for low acoustic noise, less than 1 milligauss EMI, and +/- 1 degree C temperature stability. Additionally, the first-floor laboratories achieve NIST A vibration rating. From this base, certain laboratories have been modified to provide even more stringent limits to accommodate specialized needs. For example, the TEM laboratory has tighter temperature controls, has specialized airflow patterns, and has special acoustic materials on the walls and floors.Hall Nanometrology Laboratory.
For highly sensitive functions, the Kevin G. Hall Nanometrology Laboratory provides enhanced control of temperature, vibration, acoustic noise, and EMI. Temperature is controlled to +/- 0.01 degree C, EMI is controlled to less than 0.1 milligauss, acoustic noise is within NC-35 criteria, and vibration is controlled to NIST A-1 criteria.Scanning Laser-Doppler Vibrometry.
A specialized laboratory that meets NIST A-1 vibration criteria houses the Scanning Laser-Doppler Vibrometer. The Polytec MSA-400 Micro System Analyzer uses a variety of methods to characterize motion in micro- and nanostructures.Scanning Probe Microscopy.
Nine atomic force microscopes provide topographical data on surfaces as well as allowing the manipulation of materials at the nano scale. Two systems are designed especially for analyzing biological samples, with one located in a BSL-1 laboratory and the other in a BSL-2 laboratory.Electron Microscopy.
Four electron microscopes provide the ability to image nanoscale devices and materials, as well as to study reaction mechanisms at the atomic scale. An FEI Titan 80-300 keV Field Emission Environmental Transmission Electron Microscope – Scanning Transmission Electron Microscope provides resolutions to 0.7 by 1.0 Angstrom units. The system contains an in-situ reaction chamber, and is equipped with a high-performance camera and data server.
Supplementing the capabilities of the Titan are an FEI Field-Emission Scanning Electron Microscope, an FEI “Novalab” Focused Ion Beam – Scanning Electron Microscope system, and a dual-function JEOL Scanning Electron Microscope with electron-beam direct-write capability.Surface Analysis.
The surface analysis laboratory contains a Kratos Imaging x-Ray Photoemission Spectrometer (XPS) with an in-situ reaction cell and an Omicron surface analysis cluster tool. The XPS has a 15 micrometer spot size, and provides atomic-level analysis of materials. The cluster tool contains multiple devices to characterize the surfaces of materials, including a high-resolution electron-energy-loss spectrometer (EELS), a scanning electron microscope (SEM), a scanning auger spectrometer, a hemispherical electron spectrometer for XPS, AES, UPS, ISS, a focused ion beam (FIB) system and an Omicron UHV Scanning Tunneling Microscope – all connected under ultra-high vacuum.x-Ray Diffraction.
The x-ray diffraction laboratory contains a high-resolution PANalytical “x”Pert Pro x-ray diffraction system.Epitaxy.
Several BNC laboratories contain equipment for specialized, highly precise epitaxial growth. Two ultra-clean Molecular Beam Epitaxy systems for III-V epitaxy, an Epigress VP-508 hot-wall CVD reactor for SiC and graphene, and an Aixtron AIX 200/4 metal-organic chemical vapor deposition (MOCVD) system for GaN allow the growth of a variety of homoepitaxial and heteroepitaxial materials.Deposition.
An ASTeX plasma-enhanced chemical vapor deposition system allows film growth of specialized materials. A specialized Parylene deposition system deposits type C and N polymer onto a variety of substrates.Biosafety Level 2 Laboratories.
The BNC has five biosafety level 2 (BSL-2) laboratories, one containing two smaller tissue-culture rooms for processes involving pathogenic work and one for BioMEMS research. The biocleanroom also houses a small BSL2 cell culture room for work requiring live cells in a pharmaceutical-grade environment. These specialized laboratories allow for the safe handling of pathogenic biological materials used in the development of devices and delivery methods. One of the BSL-2 laboratories is dedicated to human/mammalian cell culture, including human and animal blood and tissue, while another is dedicated to bacterial culture work.Biosafety Level 1 and Nanochemistry Laboratories.
The BNC provides three laboratories rated at biosafety level 1 (BSL-1) for less hazardous nano-bio and nanochemistry research – including the main biocleanroom space. These laboratories are used for both mechanical and wet-chemical research activities.Electrical Characterization Laboratories.
A significant amount of BNC laboratory space is allocated to electrical characterization. From an 8 Tesla, liquid-helium-cooled Hall Effect measurement system to multiple shielded probe stations with hot and cold testing capabilities, these laboratories provide the equipment and facilities necessary to evaluate new materials, structures, and devices. We also offer a Lakeshore planar magnetic probe station.Laser Laboratories.
Specialized laboratories for optical materials development, optically enhanced deposition, and optical characterization methods have been implemented in the BNC. Using lasers of various power levels – up to Class 4 – BNC researchers are able to develop materials, processes, and devices for energy conversion and other applications. These laboratories also support research strengths in nanoelectronics and nanophotonics.Nanoincubator Laboratory.
The BNC provides flexible laboratory space that can be leased by companies through the Purdue Research Foundation. This space is designed to provide a secure, specialized laboratory for companies wishing to use the infrastructure of the BNC while maintaining private laboratory space for specialized or proprietary work.
