Effect of Plasma Etching Depth on Subsurface Defects in Quartz Crystal Elements

open access: yesCrystals, 2023
After the plasma etching of quartz crystal, the crystal lattice underwent changes in response to the length of plasma etching time. The lattice arrangement of quartz crystal was the most orderly after plasma etching for 1000 nm, and with the increase in ...
