Fabrication of Magnetic Nanostructures on Silicon Nitride Membranes for Magnetic Vortex Studies Using Transmission Microscopy Techniques
(MyJove Corp., 2018-07-02)
Electron and x-ray magnetic microscopies allow for high-resolution magnetic imaging down to tens of nanometers. However, the samples need to be prepared on transparent membranes which are very fragile and difficult to ...
Research Update: Focused ion beam direct writing of magnetic patterns with controlled structural and magnetic properties
(AIP Publishing, 2018-06-01)
Focused ion beam irradiation of metastable Fe78Ni22 thin films grown on Cu(100) substrates is used to create ferromagnetic, body-centered cubic patterns embedded into paramagnetic, face-centered-cubic surrounding. The ...
Catalyst–substrate interaction and growth delay in vapor–liquid–solid nanowire growth
(IOP Publishing, 2018-03-26)
Understanding of the initial stage of nanowire growth on a bulk substrate is crucial for the rational design of nanowire building blocks in future electronic and optoelectronic devices. Here, we provide in situ scanning ...
Comparative study of plasmonic antennas fabricated by electron beam and focused ion beam lithography
(Springer Nature, 2018-06-25)
We present a comparative study of plasmonic antennas fabricated by electron beam lithography and direct focused ion beam milling. We have investigated optical and structural properties and chemical composition of gold ...
Invited Article: Direct phase mapping of broadband Laguerre-Gaussian metasurfaces
(AIP Publishing, 2018-11-01)
We report on the fabrication of metasurface phase plates consisting of gold nanoantenna arrays that generate Laguerre-Gaussian modes from a circularly polarized Gaussian input beam. The corresponding helical phase profiles ...
