In-situ Nanoscale Characterization of Composition and Structure during Formation of Ultrathin Nickel Silicide
Tuan T. Tran, Christian Lavoie, Zhen Zhang +1
We characterize composition and structure of ultrathin nickel silicide during formation from 3 nm Ni films on Si(100) using in-situ high resolution ion scattering and high resoluti…
In-situ characterization of ultrathin nickel silicides using 3D medium-energy ion scattering
Tuan Thien Tran, Lukas Jablonka, Christian Lavoie +2
We demonstrate a novel approach for non-destructive in-situ characterization of phase transitions of ultrathin nickel silicide films using 3D medium-energy ion scattering. The tech…
Non-localized states and high hole mobility in amorphous germanium
Tuan T. Tran, Jennifer Wong-Leung, Lachlan A. Smillie +3
Covalent amorphous semiconductors, such as amorphous silicon (a-Si) and germanium (a-Ge), are commonly believed to have localized electronic states at the top of the valence band a…
Synthesis of strain-relaxed Ge-Sn alloys using ion implantation and pulsed laser melting
Tuan T. Tran, Quentin Hudspeth, Yining Liu +6
Ge-Sn alloys with a sufficiently high concentration of Sn is a direct bandgap group IV material. Recently, ion implantation followed by pulsed laser melting has been shown to be a…
Electronic interaction of slow hydrogen and helium ions in the nickel-silicon system
Tuan Thien Tran, Lukas Jablonka, Barbara Bruckner +6
Electronic stopping cross sections (SCS) of nickel, silicon and nickel-silicon alloys for protons and helium (He) ions are studied in the regime of medium and low energy ion scatte…
