摘要：

Epitaxial deposition of W(110) was achieved for the first time by pulsed laser deposition on Al2O3(1120BAR). The growth mode was studied by RHEED. Detailed ex-situ X-ray analysis was performed on films of 20-50 nm thickness. In all samples the W(110) films were found to be unstrained with the W having the bulk lattice parameters. The epitaxy of W(110) is explained in terms of the W atoms sitting in the vacant octahedral sites of the Al2O3(1120BAR). Twinning was observed in some samples.
