2060109010042 ; 工程與系統科學系 ; III-V semiconductor GaP nanobelts were synthesized with a Fe2O3 catalyst on Si substrates by thermal evaporation at high temperatures. These nanobelts, typically, have a width from 50 to 600 nm and a length of up to several hundred micrometers. Their thickness varies from 10 to 40 nm. A vacancy ordering structure was observed near the edge of the GaP nanobelts. The vacancy ordering structure was analyzed using high-resolution transmission electron microscopy, electron diffraction patterns, and computer simulation. The unit cell of the vacancy ordering structure in the GaP belt is orthorhombic with lattice parameters a=3.767 Angstrom, b=6.525 Angstrom, c=18.456 Angstrom, and alpha=beta=gamma=90degrees. In the [111] projection, the structure is a Rroot3x root3 120degrees superstructure, while in the [211] projection, it exhibits a superstructure in both the ((11) over bar3) and ((2) over bar3 (1) over bar) planes. This defective structure can also be visualized as a long period structure with a superstructure in the (111) stacking plane. (C) 2004 American Institute of Physics. |
