The roles of argon addition in the hot filament chemical vapor deposition system
Autor: Z.D. Lin, X.F. Peng, Yufeng Zhang, Qiaojun Gao, FaFa Zhang
Publikováno v: Diamond and Related Materials. 10:1523-1527
Nano-crystalline diamond films were successfully deposited using CH4/H2/Ar gas mixture by hot filament chemical vapor deposition (HFCVD) method. The characterizations of the as-grown films are carried out by using field emission scanning electron mic

The crystallographic relationship of heteroepitaxial diamond films on scratched silicon substrates
Autor: Qiaojun Gao, X.H. Pan, L.P. You, FaFa Zhang, Z.D. Lin, X.F. Peng
Publikováno v: Diamond and Related Materials. 6:1836-1840
By using the straight hot filament chemical vapor deposition method with one falt horizonatal filament, diamond films were rapidly grown on a scratched silicon substrate. Observing two kinds of interface structures of the samples by cross-section hig

Direct observation of surface atomic reconstruction by pulsed-laser heating
Autor: Qiaojun Gao, Tien T. Tsong
Publikováno v: Physics Letters A. 117:132-136
Surface atomic reconstruction of Pt and Ir surfaces, induced by pulsed-laser heating, can be directly observed in the field ion microscope. The (1 × 1) Pt and Ir (110) planes prepared by low temperature field evaporation can be reconstructed to the

How atoms move in the (1 × 1) to (1 × 2) surface reconstruction of fcc (110) planes
Autor: Tien T. Tsong, Qiaojun Gao
Publikováno v: Surface Science. 182:L257-L262
The result of a recent study of atomic steps in the (1 × 1) to (1 × 2) surface reconstruction of Pt and Ir (110) planes using ns pulsed-laser heating can only be understood by highly correlated jumps of atoms within a small [110] atom-row. We argue
