 nGimat's deposition technology is uniquely suited for the development and manufacture of thin film polymer and nanocomposite structures. Through associated development efforts in thin film polymers and nanopowders, nGimat has demonstrated the ability to produce nanopowders (< 10 nm in diameter) and thin dense polymer coatings (50 nm to 10 microns in thickness). By combining these processes, nGimat has pioneered a method for continuous, single-step fabrication of nanocomposites. In addition, the co-deposition process enables higher particle loadings, better particle homogeneity, less particle agglomeration, and thinner composites than is possible with conventional manufacturing techniques. These advantages translate into potential performance advantages while maintaining the economic feasibility of continuous, scalable production. nGimat is currently developing its CCVD and NanoSpraySM processes to develop organic LEDs and organic embedded capacitors. Each of these applications presents a significant market opportunity, but challenging performance and cost targets must be overcome. nGimat's unique deposition technology and engineered nanocomposites address these current limitations. Specifically, nGimat's organic LED layers have the potential to enhance emission efficiency through nanoparticle charge carrier injection. The fact that the emission spectrum can be tailored through polymer selection and nanoparticle properties provides additional flexibility. By tailoring the wavelength of emitted light, composite properties can be modified to fill the needs of a wide variety of applications from flat panel displays to overhead lighting. Additionally, nGimat utilized this nanoengineering principle to produce artificial dielectrics for organic embedded capacitor applications. nGimat's MagiCapTM technology utilizes polarization within the dispersed nanoparticles to simulate a true dielectric material while maintaining the low temperature processibility of a polymer. Preliminary research has demonstrated exceptional relative dielectric constants (>100) and capacitance densities (>50 nF/cm2). This combination of properties is not found in other current capacitor materials, where ferroelectric oxides require high temperature processing and polymer/ferroelectric composites have limited capacitance densities.
