Inorganic broccoli
Remco van Erp, Pirouz Sohi, POWERLAB

Like many others during the confinement, we discovered our green fingers and started to grow fresh vegetables in the backyard. After some failed attempts, we discovered that this micro-broccoli grows surprisingly well at 1050 °C! Picture is an SEM image of GaN crystals grown on a patterned silicon substrate using MOVPE.

Corona capacitor
Amir Youssefi, LPQM

Corona is everywhere! A clamp tapered high-Q electro-mechanical capacitor fabricated in CMI after CVOID-19 lockdown.

Nanodots printer
Ping Che, LMGN

Cobalt nanodots lattice was printed by ebeam writing and lift-off process on membrane. The layer of MMA/PMMA was peeled away in lift-off process in this image. With the cobalt nanodots lattice, spin spiral structure called “skyrmions” will be formed into lattice. Each skyrmion works as storage unit. Would you like to have a nano-printer for data storage?

Welcome back to CMi
Georges-André Racine, CMi

To honor the gradual exit out of the Covid-19 lock-down and to celebrate the re-opening of the CMi for users, arrays of nano-pillars were added to a first print of the resolution test of the VPG200 laser writer after its re-start in the last days of April. Direct sunlight diffraction creates nice colored rainbow arcs. Structure was recorded in 600nm thick photo resist on a silicon substrate. The diameter of the rainbow arcs is 19mm.

3-Floor Micro Apartment
Niyazi Ulas Dinc, LO

This 3-floor structure, fabricated with two-photon polymerization (Nanoscribe), is not the most welcoming home even though it is coated with gold (to see it better). But, it can do angular multiplexing with light!

A sun full of stars
Miguel Solsona, Benoît Desbiolles, Clémentine Lipp, LMIS4

This nanopore etched in SiO2 is an open window to another galaxy. You are met with an insight full of stars when you glance through it.

Micreux Jazz Festival
Robin Groth, LPQM

The CMi festival for micro-music hast just announced this year’s headliner: “The SiNs”. The newcomer band will certainly attract a large audience, not least thanks to its exotic instruments including the fractal guitar shown in the picture. When skilfully plucked, the oscillating string creates a psychedelic sound which has impressed crowds across the globe. The peculiar vibrations arise due to the self-similar geometry of the structure, which was made from silicon nitride and measures only 20nm in thickness. Rumour has it that “The SiNs” will use the festival to showcase the world’s first fractal drum.
