Alumina is a technologically important oxide crystal because of its use as a catalyst and as a substrate for microelectronic applications. A precise knowledge of its surface atomic structure is a prerequisite for understanding and contro... C Barth,M Reichling - 《Nature》 被引量: 417发表: 2001...
Simple expressions for the activation enthalpies for diffusivity and electrical conductivity, that can be parameterised from the results of local structure spectroscopies, are introduced. Particular consideration is given to the effect on transport properties of replacing silica with alumina and of ...
In this study, we employed this advanced imaging technique to probe the local atomic structure of amorphous shear bands in deformed B4C. Raman spectroscopy of amorphous B4C. In this study, the amorphous B4C was introduced by a nanoindentation experi- ment14,16,17,19. Figure 2 shows the ...
Atomistic modeling was used to investigate the energetics and structure of the Bagaryatskii orientation relationship between ferrite and cementite within pearlite. The atomic level results show that the interface structure consists of a rectangular array of dislocations that lie along the high symmetry di...
