Hillock defect
WebFeb 1, 1987 · From the line scan analysis of EPMA, the "precipitate hillock" is composed of a region with an aluminum content which is greater than the surrounding normal region, but with a lower gallium and arsenic content. It is also found that the density of "whisker" defects and "precipitate hillock" defects decrease with a rise in the growth temperature.
