Title
Atomic Scale Characterization and FirstPrinciples Studies of Si3N4 Interfaces (Springer Theses),Used
Delivery time: 8-12 business days (International)
This thesis presents results from a combined atomicresolution Zcontrast and annular brightfield imaging and electron energy loss spectroscopy in the Scanning Transmission Electron Microscopy, as well as first principles studies of the interfaces between crystalline Si3N4 and amorphous (i) CeO2x as well as (ii) SiO2 intergranular film (IGF). These interfaces are of a great fundamental and technological interest because they play an important role in the microstructural evolution and mechanical properties of Si3N4 ceramics used in many high temperature and pressure applications. The main contribution of this work is its detailed description of the bonding characteristics of light atoms, in particular oxygen and nitrogen, at these interfaces, which has not been achieved before. The atomicscale information on the arrangement of both light and heavy atoms is critical for realistic modeling of interface properties, such as interface strength and ion transport, and will facilitate increased control over the performance of ceramic and semiconductor materials for a widerange of applications.
