T. Kizuka et al., TIME-RESOLVED HIGH-RESOLUTION ELECTRON-MICROSCOPY OF SOLID-STATE DIRECT BONDING OF GOLD AND ZINC-OXIDE NANOCRYSTALLITES AT AMBIENT-TEMPERATURE, Applied physics letters, 70(8), 1997, pp. 964-966
Approach, contact, and bonding processes between different kinds of ma
terials, gold (Au) and zinc oxide (ZnO) nanocrystallites were observed
at atomic scale and at time resolution of 1/60 s. The nanocrystallite
s contact spontaneously when they approach at a few atomic distances u
nder an intense electron irradiation. It was found that a Au/ZnO inter
face forms at ambient temperature without any sintering aid after the
contact. (C) 1997 American Institute of Physics.
