摘要: Abstract The periodic instability of the diameter whiskers grown by vapor-liquid-solid (VLS) mechanism is studied. This phenomenon especially distinct for silicon and, to a lesser degree, germanium whiskers. develops only in submicron (≲ 0.5 μ) diameters, smaller mean diameter, more periodicity, i.e. it occurs range sizes where Gibbs-Thomson effect manifests itself. occurrence related experimental conditions such as crystallization temperature, supersaturation and impurities. Some morphological details are also A working hypothesis explain presented.
