The surface between grains is usually a region of increased electrical potential compared to the bulk, so that a barrier to conductivity occurs across the boundary. These grain boundary potentials are often called Schottky barriers. The height and form of the barrier depends sensitively upon the materials in contact. [Pg.122]

Figure 12 An interface in 2212 showing atomically sharp high angle grain boundary with grain to grain connectivity. The diffraction pattern from the grains is inset. Grain B is 2212 phase and grain C is strontium-copper oxide. Figure 12 An interface in 2212 showing atomically sharp high angle grain boundary with grain to grain connectivity.

Fig. 5.5 (a) About 20 atomic layers of Co are vapor deposited on the tungsten tip surface shown in Fig. 5.4, and then annealed to 700°C for 60 s. It appears that an ordered W-Co alloy is formed on the tip surface and also in the grain boundaries. The grain boundaries are widened by diffusion of Co atoms into the boundaries. [Pg.328]

Figure 9.8 Isolated-boundary (Type-B) self-diffusion associated with a stationary grain boundary, (a) Grain boundary of width 6 extending downward from the free surface at y = 0. The surface feeds tracer atoms into the grain boundary and maintains the diffusant concentration at the grain boundary s intersection with the surface at the value cB(y = 0, t) = 1. Diffusant penetrates the boundary along y and simultaneously diffuses transversely into the grain interiors along x. (b) Diffusant distribution as a function of scaled transverse distance, xi, from the boundary at scaled depth, yx, from the surface. Penetration distance in grains is assumed large relative to 5.

Nucleation on Grain Boundaries, Grain Edges, and Grain Corners... [Pg.477]

Special nucleation sites on grain boundaries, along grain edges, and at grain corners. [Pg.105]

Eq. (62) can take account of the dielectric response of a boundary (electrode, grain boundary) but would not be sufficient to describe bulk polarization phenomena (appearing at longer times or lower frequencies) induced by strongly selectively blocking electrodes or grain boundaries (see below). The latter effect will be touched upon in the next section. [Pg.78]

It is fairly obvious that this phenomena must be related to the fact that the poly is made up of many small grains with their attendent grain boundaries. Each grain is a single crystal and should behave as the epi films do. Therefore, the cause of the increased resistivity must involve the grain boundaries. [Pg.81]
