This facility contains two core systems.
A Sputter deposition system and a maskless lithography system provide researchers the capacity to create their desired patterns
in their choice of metals.AJA International Inc’s Polaris sputtering system has a 750 watts DC power source for the target gun
and a 100 Watts RF power source for creating RF plasma to clean samples. Metal films of thickness in the range 0.2 µm – 2 µm can be deposited using
the DC power source. Future upgrades planned for this system will allow for the deposition of both conducting and insulating thin films.
The maskless lithography system has the capability to create features with a resolution of 5 µm. The innovative smart filter on this system eliminates the
need for expensive physical masks for creating desired patterns on a given substrate. The microfabrication lab is equipped to carry out both wet-etch
and lift-off processes for creating patterns/circuits on planar and non-planar substrates.

Raman spectroscopy is a powerful technique for probing the local atomic environment in a wide variety of materials
by detecting the phonon vibrations through the material. Particularly sensitive for carbon-based materials.
It is complementary to the FT-IR technique.

The 1.2 KW, 6 KW Microwave Plasma Chemical Vapor Deposition systems are utilized for growing single crystal and nanocrystalline diamond
on various substrates such as diamond, silicon, and titanium alloys. Shown to the left is the 1.2 KW CVD system.
This system is primarily used for growing homoepitaxial diamond for the purpose of fabricating designer diamond anvils
utilized in high-pressure research.

The Force-5 (AMTI, Inc.) wear simulation instrument for the testing of materials for biomechanical applications, such as the evaluation
of joint replacement implants. The machine can be set up to test various types of devices such as hips, knees, and temporomandibular joints.
The motion can be programmed to mimic the complex motion of these implants and uses feedback to control the motion.
With a maximum vertical load of 1000lbs. and 4 independently controlled axes of motion, the machine can replicate patterns of motion such as walking
or chewing using a user-configurable computer control. A six-axis load cell gathers force and displacement data for analysis.
The joint in testing can be maintained in a temperature-controlled, fluid-filled environment for proper biomechanical considerations.

The Panalytical Empyrean Multi-purpose X-ray diffractometer has the capability to analyze many types of samples, including powders,
thin films, and epitaxial films. Samples can be analyzed in reflection or transmission and the instrument is outfitted with multiple stages
including a 3-axis stage and a reflection/transmission spinning stage. Other types of analysis include small angle X-ray scattering (SAXS),
micro-diffraction (~300um spot size), and high-resolution single crystal analysis, such as pole figures and reciprocal space mapping (RSM).
The instrument has two detectors: an array detector for fast powder diffraction scans and RSM as well as a standard proportional detector
with a parallel plate collimator for thin film scans. Multiple optics are available including the BBHD (standard optic with beta filtering),
a monochromator for high resolution scans, a focusing mirror for SAXS and transmission scans, and the micro-diffraction optic.

The Quanta 650 FEG scanning electron microscope (SEM) was purchased in 2012 with an NSF-MRI grant for $550,000 and is located
at the School of Engineering. The SEM provides high resolution images with resolution down to the nanometer range.
It can image samples ranging from metals to biological samples and even wet materials. It also can perform energy-dispersive x-ray analysis (EDAX)
to provide elemental composition. Non-conducting samples can be imaged with the aid of the new sputter coater which deposits a
thin layer of gold-palladium on the surface to improve imaging.

The Horiba Scientific Fluorolog 321 double grating spectrometer with TE-cooled photomultiplier will be used for high sensitivity
fluorescence detection upon Troponin adsorption. This system has a solid sample and custom microscope coupling optics/slits
to allow fluorescence mapping at the sub-micron level using an attached Zeiss fluorescent microscope with custom camera
and spectrometer interface components.

The core technology of the VersaProbe 5000 is PHI’s patented, monochromatic, micro-focused, scanning x-ray source
which provides excellent large area and superior micro-area spectroscopy performance. Spectroscopy, depth profiling,
and imaging can all be performed over the full range of x-ray beam sizes including the minimum x-ray beam size of 10 μm.
Multi-technique options include chemical mapping, quantitative elemental analysis, a hot/cold sample stage, and sample treatment chambers.
