Transmission electron microscopic observation of microdefects in Zn+-implanted GaAs

  • 1. Sony Corp., Yokohama (Japan). Research Lab.

Description

Transmission electron microscopic (TEM) observation of GaAs implanted with 100 keV Zn+ ions to 1014 ∼ 1015 ions/cm2 and annealed at 650 ∼ 950 deg C by capless annealing in As ambient revealed precipitates, stacking-fault tetrahedra (SFTs) and stacking-fault pyramids (SFPs). The precipitates, distributed from near Rp to greater depths, consisted of non-crystalline material of mean inner potential smaller than that of GaAs. Defects showing black-white contrast were found to be SFTs accompanied by a precipitate or SFPs. Two types of SFTs can be differentiated by the core structure of their stair-rod dislocations. Most of the SFTs observed were identified as β-SFTs and very few SFPs were observed. (author)
