We develop a broadband and omnidirectional tunable resonators with polarization-free high light absorption by preparing a hexagonally patterned array of free-standing SiO2_Ag core-shell nanoparticles. It is the result of hybrid optical modes consisting of Plasmon modes and whispering gallery modes.

INTERMAG 2021

technical paper

The International Conference on Electron, Ion and Photon Beam Technology and Nanofabrication (EIPBN), affectionately known as "3-Beams," is the premier gathering of scientists and engineers who are dedicated to electron, ion and photon lithography, imaging, and analysis; atomically precise fabrication; nanofabrication process technologies and related emerging technologies; and their applications in a broad spectrum of fields. In its 64th meeting, researchers from academia, government laboratories, and industry from around the world meet to present and discuss recent and future trends in these technologies.

A two-dimensional array of transmissive microshutters is designed in which light throughput can be digitally modulated at each pixel. This function is important for certain instruments, such as the near infrared spectrometer to be carried on the James Webb Space Telescope, microscopes, telephoto lenses, or digital light processors.

As the thickness of the vibrating structures is reduced, the built-in strain of the structural materials plays an increased role in determining the mechanical performance of the devices. Here we demonstrate the realization of ultrathin doubly clamped nanomechanical resonators with an axial strain in the scale of 10^8.

Current networks of neurons show a biology, which represents functions similar to those reported for fetal human brain. Human brain modelling on chip can shine light on in vivo-like message passing from neuron to neuron in a dish.

Here, we will show the application of Cryo-FIBID to other precursors beyond W(CO)6, with the aim of obtaining ultrafast growth of metallic deposits, and eventually additional functional properties. In particular, we will discuss the results obtained using the (CH3)3Pt(CpCH3) precursor, which is commonly found in commercial FIB equipment.

CMOS back-end-of-line integration is a very promising technology for the next generations of integrated circuits. Yet, electron beam lithography and alignment on multiple underlying metal layers and structures is challenging. In this paper, we present an image correlation strategy, procedure and markers to reach alignment accuracy better than 5 nm.

Using high current focused Xe ion beam milling we fabricated ultra-deep and high quality micro-axicons in such a challenging material for microfabrication as lithium niobate. The axicons generate sub-wavelength focused beam over extended depths of focus with potential applications in microscopy and particle trapping.

Our goal in this paper is to demonstrate a process flow for the fabrication of silicon tips using KOH based wet etching and Cryo or Bosch based dry etching approaches.

Fabrication of Silicon Micro Tips for Microbial Cell Lysis Applications

We have developed a new technology for detecting single DNA molecules on-chip. A nanofluidic device was fabricated in a multi-step process to unfold the molecules in 3D inlets and guide them inside the nanochannels. No external field is applied, allowing high throughput and generate enormous data in real-time.

Blood separation and processing is a vital and essential step in numerous medical and clinical tests. We present here a unique deformable nanodevice functionalized by three-dimensional (3D) microbeads for plasma separation and blood cells retrieval.

Label-free optical observation of transparent nano-objects is challenging. We present PlAsmonic NanO-apeRture lAbel-free iMAging (PANORAMA) to image, size, count and monitor single nanoparticle with a size limit approaching sub-10 nm. Molecular imaging is envisioned with functionalized substrates for single nanoparticle analysis for extracellular vesicles (e.g., exosomes) and pathogens (e.g., viruses).
