Remote surface roughness scattering
WebThe average surface roughness (Ra) of the component ranges from 3 μm to 10 μm with stair-stepping effects, balling on surfaces resulting in poor dimensional accuracy. Therefore, post-processing methods like abrasive flow finishing, laser polishing, chemical polishing and traditional finish machining is often used to meet the desired surface integrity and … WebIn this work, remote surface roughness !RSR" scattering mediated by the high polarization is studied as a new scattering mechanism in such structures. In both depletion-mode and …
