This Phase I project has two primary objectives. The first objective is to evaluate the feasibility of a fully ion implanted fabrication process based on the heterodimensional 2-D MESFET. The new device, the 2-D JFET, will have p+ ion implanted sidegates which laterally modulate a thin, highly doped n-type conducting channel. The 2-D JFET should have excellent high speed, low power characteristics ...

Novel ionic self-assembled monolayer (ISAM) processes for the fabrication of advanced electronic materials and devices will be developed through this program. Revolutionary ISAM methods to create nanostructured multi-layer inorganic/organic thin-films offer major advantages over conventional manufacturing processes, since the process is simple, low-cost and environmentally friendly in that no vola ...

F&S and Virginia Tech will cooperatively develop high performance protective ionic self-assembled monolayer (ISAM) organic/inorganic coatings for space-based optical and structural components, and work with Litton to upscale practical coating manufacturing. Revolutionary ISAM methods of creating multi-layer protective nanopartwcle films offer major advantages over con-ventional coating processes, ...

Aerospace composite panels containing a core structure usually use an expanded honeycomb of either aluminum, NOMEX, or carbon fiber. These types of composite panels are often used as structure since the honey-comb core provides stiffness in the "Z" direction. However, they provide no thermal insulation value. Aerospace craft operating both inside and outside the earth's atmosphere experience envir ...

Currently manufactured aerospace composites absorb water vapor to varying degrees. This moisture absorption adds weight to the composite, however, it lowers the glass transition temperature. And, subsequently, the ultimate strength of the resin holding the composite together, in the total composite matrix. For aerospace vehicles that slip the bonds of Earth and enter the vacume of space, any compo ...

This Small Business Innovative Research Phase I project will focus on the development of a compact, rugged, low-maintenance, cost-effective, all Solid-State Raman Image Amplifier (SSRIA) capable of amplifying low-level LIDAR images and producing gated images with potential gate times of less than a nanosecond. The innovative technology to be implemented is based on a solid-state stimulated Raman s ...

We propose to design and fabricate an adaptive beam expander that can be switched between two magnifications. Specifically, the beam expander provides diffraction-limited performance for laser radar beams with diameters of 1 mm and 3 mm. The adaptive beam expander is lightweight, and it has no moving parts. Because the beam expander is an afocal system, it operates on both outgoing and incoming be ...
