Surface Shaping by Ion Beams at Grazing Incidence: Simulations vs. Experiment
Miniaturization of electronic technologies highlights special approaches such as selforganization of nanostructures. Particularly, surface etching by ion beams at grazing incidence is of interest for applications, because it provides pronounced submicron size, self-organized ripples. Formation [...]
Ab Initio Simulation on Deposit Process of Al on Si Surface
It is important to clarify structure of contact between different materials for evaluation of properties of interfaces, which are substantial in electronic devices. Since interaction between different materials has to be evaluated based on the [...]
Periodic Lattice Distortion in YBa2Cu3O7 50 nm film on SrTiO3
Synchrotron X-ray diffraction has been used to detect novel periodic lattice distortions (PLD) in highly c-axis oriented YBa2Cu3O7 (YBCO) 50 nm films grown on SrTiO3 substrate. The growth layer by layer of 50 nm YBCO, [...]
Nanostructured Metallic Thin Films: Measurement of Critical Exponents
We have deposited metallic films (Au, Pt) on silicon substrates. The deposition technique was the Metal Plasma Immersion Ion Implantation and Deposition. Their roughnesses have been measured using a Scanning Tunneling Microscope. From these roughnesses, [...]
MEMS Fabrication Modeling with ChISELS: A Massively Parallel 3-D Level-Set Based Feature Scale Modeler
We are developing ChISELS (Chemically Induced Surface Evolution with Level-Sets), a parallel code to model 3-D material depositions and etches at feature scales on patterned wafers at low pressures. ChISELS is a platform on which [...]
Preparation and Characterization of New Lanthanide materials: Layered Double Hydroxide Intercalated by Luminescent Polyoxometalate Anions with Dawson-like [Eu(H2O)3(a2-P2W17O61]7- and Keggin-like [Eu2(H2O)2(PW11O39)]4-
Dawson-like [Eu(a1-P2W17O61]7-and Keggin-like [Eu2(PW11O39)2]8-were first isolated and x-ray crystallized in our group. In relation to previous work, we are interested in synthesizing new lanthanide materials by incorporating the title polyoxometalates (POMs) anions into layered double [...]
Nanopatterning of Periodically Strained Surfaces – A Kinetic Monte Carlo Simulation Study
We present kinetic Monte Carlo simulations of nanopatterning by using strain-assisted nucleation of adatom islands on periodically strained fcc(111) surfaces. The goal of our work is to predict conditions and limitations for producing nanopatterns. It [...]
Optimizing Processing Conditions to Influence the Morphology of Nanocomposite
In recent years, the area of nanocomposites has received considerable attention with the expectation that nanotechnology can lead to lighter, better materials for engineering applications. For example, the attractiveness of polymer-clay nanocomposites resides in the [...]
Next Generation Aerospace Composites Through Nanotechnology
Polymeric nanocomposites are a relatively new class of materials obtained by dispersing inorganic layered silicates in polymer matrix. Generally well-dispersed exfoliated morphology of clay platelets in nanocomposite is sought with the expectation that this would [...]
Chemically Functionalized Clay Epoxy Nanocomposites for Aerospace Applications
Reinforcement of polymeric resin with nanoclay platelets has resulted in lightweight materials with enhanced mechanical and thermal properties. The selection of clay as reinforcing material is extremely appealing because of cost, high thermal inertness, and [...]
Multivariant Measurements for Thin Film Adhesion as a Function of Temperature and Thin Film Thickness
The progress of a proposed high-throughput combinatorial approach to the edge delamination test is reported. This approach can construct the adhesion reliability, as a function of temperature and film thickness (in the sub-micron range) in [...]
Surface Modification of Al203 Fiber with Nanoparticles Using a Dry Mechanical Coating Technique
Coowanitwong N., Wu C-Y, Nguyen J., Cai M., Ruthkosky M., Rogers J., Feng L., Watano S., Yoshida T., University of Florida, US
Nanoparticles are of great interest to many industries due to their unique properties. One of the well-known properties is high surface area, which is critically essential to enhancing performance activity [1] and greatly vital to [...]
