EBIC MEASUREMENTS ON LOW ANGLE GRAIN BOUNDARIESA. BARY et G. NOUET

The largest grains in Polix ingots contain several low-angle grain boundaries. The electrical properties of high angle grain boundaries have extensively been studied by EBIC/TEM techniques (1) but comparatively less attention has been paid to those of low-angle grain boundaries. However for Polix materials, in the regions of large grains, the total length of low-angle grain boundaries can be much greater than that of high-angle grain boundaries. Moreover, in general the low-angle grain boundaries exhibit strong EBIC contrasts suggesting that their electrical activity is at least of the same order of magnitude than the electrical activity of high-angle grain boundaries.
