Many MEMS … WebbThis paper presents a review of our current understanding of environmentally induced slow crack growth in glasses, single crystals, and polycrystalline ceramics. It is shown that the rate of crack growth is controlled by the chemical activity of the active species in the environment as well as by the stress intensity at the crack tip.

Webb1 sep. 2015 · Single crystal (SC) silicon is one of the most fundamental materials in semiconductor industry owing to its broad applications. A major challenge to the application of SC silicon is the reliability of its physical and mechanical properties which are determined by its structural integrity. Webb1 dec. 2015 · Further experiments on single crystal silicon have been reported recently by Jaya et al. [6] who compared four different microscale test geometries, all produced by FIB milling. The results from all four methods agreed both with one another and with the accepted macroscopic values for fracture on the relevant crystallographic plane.
