The development of new types of light sources is necessary in order to meet the growing demands of consumers and to ensure an efficient use of energy. The cathodoluminescence process is still under-exploited for light generation because of the lack of cathodes suitable for the energy-efficient production of electron beams and appropriate phosphor materials. In this paper we propose a nano-graph...

Curves as a subject of differential geometry have been intriguing for researchers throughout mathematical history and so they have been one of the interesting research fields. Regular curves play a central role in the theory of curves in differential geometry. In the theory of curves, there are some special curves such as Bertrand curves, Mannheim curves, involute and evolute curves, and pedal ...

This work presents a highly effective approach for the chemical purification of directly written 2D and 3D gold nanostructures suitable for plasmonics, biomolecule immobilisation, and nanoelectronics. Gold nano- and microstructures can be fabricated by one-step direct-write lithography process using focused electron beam induced deposition (FEBID). Typically, as-deposited gold nanostructures su...

To date, nano-and micro-structuring has commonly been implemented by a combination of specifically optimized processes of electron-beam lithography and reactive ion etching, thus limiting the range of materials that can be structured to only a few. In this talk we will introduce focused ion beam (FIB) milling as an emerging technology that enables fast, reliable and well-controlled nanometer-si...

We report easy to implement techniques for the fabrication of high aspect ratio LiNbO3 photonic crystals. The methods rely on optical grade dicing followed by focused ion beam (FIB) milling. A 2D photonic crystal with an extinction ratio of -14dB is demonstrated. We show how the techniques can be combined for the development of 3D photonic crystals. LiNbO3, ridge waveguides; photonic crystals,

Nanochannels fabricated in fused silica substrates are ideal tools for single (bio)molecular studies in biology and are promising in the development of innovative applications in chemistry. To obtain a higher throughput and a higher level of integration and functionalization, nanochannels with high aspect ratios and nano-in-nano structures are very much desired, but their fabrication is a chall...

Understanding magnonic properties of nonperiodic magnetic nanostructures requires real-space imaging ferromagnetic resonance modes with spatial resolution well below the optical diffraction limit and sampling rates in 5--100 GHz range. Here, we demonstrate element-specific scanning transmission x-ray microscopy-detected (STXM-FMR) applied to a chain dipolarly coupled ${\mathrm{Fe}}_{3}{\mathrm{...

We propose and demonstrate a scheme that enables spectral tuning of a photonic crystal high-quality resonant mode, in steps finer than 0.2 nm, via electron beam induced deposition of carbonaceous nano-dots. The position and size of a nano-dot with a diameter of <100 nm are controlled to an accuracy on the order of nanometers. The possibility of selective modal tuning is also demonstrated by pla...

Room-temperature ionic liquid (RTIL) has been widely investigated as a nonvolatile solvent as well as a unique liquid material because of its interesting features, e.g., negligible vapor pressure and high thermal stability. Here we report that a non-volatile polymerizable RTIL is a useful starting material for the fabrication of micro/nano-scale polymer structures with a focused-ion-beam (FIB) ...
