Mask-less Patterning of Gallium-irradiated Superconducting Silicon Using Focused Ion Beam
Ryo Matsumoto, Shintaro Adachi, El Hadi S. Sadki +4
A direct patterning technique of gallium-irradiated superconducting silicon has been established by focused gallium-ion beam without any mask-based lithography process. The electri…

Lithography-free control of the position of single walled carbon nanotubes on a substrate by focused ion beam induced deposition of catalyst and chemical vapor deposition
El-Hadi S. Sadki, Ryo Matsumoto, Hiroyuki Takeya +1
We introduce a novel nanofabrication technique to directly deposit catalyst pads for the chemical vapor deposition synthesis of single-walled carbon nanotubes (SWCNTs) at any desir…

Focused-ion-beam-induced deposition of superconducting nanowires
E. S. Sadki, S. Ooi, K. Hirata
Superconducting nanowires, with a critical temperature of 5.2 K, have been synthesized using an ion-beam-induced deposition, with a Gallium focused ion beam and Tungsten Carboxyl,…
