Abstract:Multiphase and porous ceramic materials are being used as passive semiconductors for building modern optoelectronics devices. Prescreening of the critical parts for subsurface defects before assembly can prevent device failures in the field. A new nanoindentation based nondestructive method has been proposed where shapes of loading-unloading curves can fingerprint subsurface cracking and material porosity induced inelastic behavior in defected multiphase, rough and porous ceramic parts. In addition to the diff… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
