Ni-imprint induced solid-phase crystallization in $Si1−xGex$ (⁠$x$⁠: 0–1) on insulator Available to Purchase

Position control of solid-phase crystallization in the amorphous $Si1−xGex$ (⁠$x$⁠: 0–1) films on insulating substrates was investigated by using Ni-imprint technique. Crystal nucleation at the imprinted positions proceeded approximately 2–20 times, depending on Ge fraction, faster than the conventional solid-phase crystallization, which was due to the catalytic effect of Ni. As a result, large SiGe crystal regions $(∼2μm)$ were obtained at controlled positions. On the other hand, the growth velocity did not changed, which suggested that grown regions contained few residual Ni atoms.
