Description

<p>Our objective is to apply CVD and non-CVD carbon nanotubes to complex shapes that numerous scientists have requested for stray light control.  Currently, CVD nanotubes can only be grown on flat surfaces due to limitations in line-of-sight physical vapor deposition techniques such as e-beam evaporation.   For CVD our adhesion and catalyst layers must be applied on the on the component with extreme uniformity to a thickness of 1 to 2 nm for ideal performance.   Then the component must be placed in the thermal reactor furnace flow in a way that allows uniform exposure to the carbon bearing gas.  Our first focus area is to utilize atomic layer deposition (ALD) to apply our adhesion and catalyst layers conforming to the desired substrate surface.  This will allow fabrication of components that are dark on all surfaces instead of just on one surface.</p>
