Direct Patterning of Boron-doped Amorphous Carbon Using Focused Ion Beam-assisted Chemical Vapor Deposition
Ryo Matsumoto, El Hadi S. Sadki, Hiromi Tanaka +4
The deposition of boron-doped amorphous carbon thin films on SiO2 substrate was achieved via a focused ion beam-assisted chemical vapor deposition of triphenyl borane (C18H15B) and…
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…
Embedding a carbon nanotube across the diameter of a solid state nanopore
E. S. Sadki, S. Garaj, D. Vlassarev +2
A fabrication method for positioning and embedding a single-walled carbon nanotube (SWNT) across the diameter of a solid state nanopore is presented. Chemical vapor deposition (CVD…
Electrical transport properties of small diameter single-walled carbon nanotubes aligned on ST-cut quartz substrates
Tohru Watanabe, El-Hadi S. Sadki, Takahide Yamaguchi +1
A method is introduced to isolate and measure the electrical transport properties of individual single-walled carbon nanotubes (SWNTs) aligned on an ST-cut quartz, from room temper…
Temperature Dependence of the Electrical Transport Properties of Multilayer Graphene
E. S. Sadki, H. Okazaki, T. Watanabe +2
Multilayer graphene (MLG) thin films are deposited on silicon oxide substrates by mechanical exfoliation (or 'scotch-tape method') from Kish graphite. The thickness and number of l…
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,…
Effects of interlayer coupling on the irreversibility lines of NbN/AlN superconducting multilayers
E. S. Sadki, Z. H. Barber, S. J. Lloyd +2
We have studied the temperature dependence of the in-plane resistivity of NbN/AlN multilayer samples with varying insulating layer thickness in magnetic fields up to 7 Tesla parall…
