  • THE INTEGRATION - Cambridge University Press

    The CF4 etched sample shows a large increase, c. 20x increase over as-deposited films, in fluorine content on the surface. The small fluorine signal on the as-deposited sample is most likely due to 110 use, available at https://www.cambridge.org/core/terms. https://doi.org/10.1557/PROC-477-109 Downloaded from https://www.cambridge.org/core.

  • Atmospheric Pressure Plasma Technology For Ultra-Precision

    New optical technologies increase the demands on the engineering specifications of optical surfaces, with manufacturing specifications of up to 1nm RMS form accuracy and 0.1nm RMS surface finish. To achieve these fabrication requirements novel ultra-precision methods must be developed. The proposed solution is microwave generated activate plasma figuring.

It corresponds to the ERB-rate of 2.53 (according to Moore and Glasberg, 1983) and a stimulation range of 2.28 mm on the basilar membrane (according to Greenwood, 1990). For CF9.2, the bandwidth is double the bandwidth for CF4.6, which results in 3000 Hz.
