Ostwald ripening of Pd particles on the (101̄2̄) surface of sapphire

Morphological changes of small Pd particles on the (101̄2̄) surface of α-Al 2O 3 single crystal were investigated by Auger electron spectroscopy in the temperature range 833–923 K. It was shown that practically there was no decrease of the effective thickness during heat treatments under 6×10 −9 mba...
