Two- and Three-Dimensional Superconducting Phases in the Weyl Semimetal TaP at Ambient Pressure

Crystals, 2020
The motivation to search for signatures of superconductivity in Weyl semi-metals and other topological phases lies in their potential for hosting exotic phenomena such as nonzero-momentum pairing or the Majorana fermion, a viable candidate for the ...

Focused Ion Beam Tomography

, 2020
Para estudiar el efecto fundamental de la forma y la morfología de cualquier material sobre sus propiedades, es muy esencial conocer y estudiar su morfología. La tomografía de haz de iones enfocado (FIB) es una técnica de estudio de relaciones químicas y estructurales en 3D.

Ionic liquid ion sources for focused ion beam applications: A review

Micro and Nano Engineering
Focused ion beam (FIB) technology has transformed materials science by enabling precise micro- and nano-scale modifications through ion beam interactions. Originally developed for semiconductor doping and device fabrication, FIBs use different ionization

Helium focused ion beam direct milling of plasmonic heptamer-arranged nanohole arrays

Nanophotonics, 2020
We fabricate plasmonic heptamer-arranged nanohole (HNH) arrays by helium (He) focused ion beam (HeFIB) milling, which is a resist-free, maskless, direct-write method.

Dynamics of perpendicular recording heads [PDF]

, 2001
3D modeling and inductance measurements were used to design an ultra-high frequency perpendicular system. Kerr microscopy and spin-stand experiments with focused ion beam (FI-B) trimmed perpendicular heads and perpendicular media directly verified the ...

Microphotonic parabolic light directors fabricated by two-photon lithography [PDF]

, 2011
We have fabricated microphotonic parabolic light directors using two-photon lithography, thin-film processing, and aperture formation by focused ion beam lithography. Optical transmission measurements through upright parabolic directors 22 μm high and 10

Focused-ion-beam-induced deposition of superconducting nanowires

, 2004
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, W(CO)6, as precursor.

Focused-ion-beam fabricated vertical fiber couplers on silicon-on-insulator waveguides [PDF]

, 2006
We fabricated grating couplers in silicon-on-insulator waveguides with focused-ion-beam. First devices were very lossy, but by using selective etchant and a hard mask we obtained efficiencies comparable to traditional fabrication ...

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro

Molecular Oncology, EarlyView.
Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

Small scale tests of cement with focused ion beam and nanoindentation [PDF]

MATEC Web of Conferences, 2020
Nanoindentation is used for characterization of small scale material properties of hydrated cement. It is employed as a precise loading tool on samples fabricated with Focused Ion Beam milling (FIB).
