Nano Spaghetti & Meatballs
Colorized and overlaid scanning electron microscope images of Spaghetti & Meatballs made out of Au and Si. The 'spaghetti' is a collection of electrodeposited Au nanowires, 100 nm in diameter, that have released from the substrate and bundled together (Thomas Cornelius – GSI Darmstadt). The 'meatballs' are Si nanoparticles, ~1.5 um in diameter, with Au nanocrystals on the surface that were grown on carbon-coated substrates using ultra-high vacuum molecular beam epitaxy (Gunther Richter – MPI Stuttgart). These images highlight some of the many varied structures that can be formed at the nanoscale.

The scanning electron microscopic image (taken using a FESEM LEO 1530) shows the ZnO nanostructures on an indium oxide coated glass substrate deposited at 70oC by using a facile electrochemical deposition technique. A potentio-/galvanostat electrochemical workstation (CH Instruments 660A) was used to deposit the ZnO nanostructures by amperometry potentiostatically at -1.1 V (relative to the Ag/AgCl reference electrode) and a spiral platinum wire served as working electrode. An aqueous zinc nitrate [Zn(NO3)2.6H2O] solution was used as an electrolyte to prepare these ZnO nanostructures.

Field of Sunflowers
Amorphous SiOx nanowire bundles have an uncanny ability to self-assemble into various shapes, including one that strikingly resembles a sunflower. In these sunflowers, highly packed bundles form the disc florets and loosely packed ones around the rim of the disc form the ray florets. The SEM image shows a field of sunflowers. The grey scale image was mapped into pseudo-colors by graphic software. The nanowires grew out of the reaction of Si and oxygen, with molten Ga and Au acting as catalysts. Each nanowire is about 10 nm in diameter and tens of micrometers in length.

This is a cross-polarized light optical microphotograph of an array of organic thin-film transistors (OTFT) fabricated with newly synthesized, highly crystalline 4T-TMS organic semiconductor deposited by newly developed solution-shearing method. Besides the excellent performances these new OTFTs exhibited, this microphotograph represents itself an aesthetic landscape painting full of beauty and art: different parts of the cross polarized thin film look like lakes, lands, mountains and sunglows, while the gold electrodes of the transistors seem to be a fence between lakes and far-away mountains...

Gold Nanopyramids
High resolution scanning electron micrograph (SEM) of gold nanopyramids supported by silicon pedestals. The orientation-dependent optical properties of the nanoparticle arrays have revealed new insight into the interaction between light and materials at the nanoscale. These structures are also being explored in applications such as chemical and biological sensing and nanophotonics. Joel Henzie developed the large-area (>1 in. 2 covered by ~10 8 pyramids) nanofabrication techniques to create the pyramids while working in the Odom lab at Northwestern University . The results are published in J. Phys. Chem. B [Joel Henzie, Kevin L. Shuford, Eun-Soo Kwak, George C. Schatz, and Teri W. Odom, J. Phys. Chem. B ., 2006, 110 , 14028-14031].

“Ancient of Days” from classical art to quantum art
A 500×500 µm photoluminescence image of “Ancient of Days” was created in porous silicon using focused helium beam writing and subsequent electrochemical etching in hydrofluoric acid. Due to quantum confinement effect, visible light emission is observed from the nanosized silicon skeleton left behind after etching. It is found that pre-irradiation with a helium beam is able to change the local resistivity of the silicon and the emission wavelength of the porous silicon formed. The higher the dose of the beam, the redder the photoluminescence wavelength becomes. Here, we see that the figure of the man is depicted in orange and his face and masculinity is highlighted by the black outline created using high dose irradiation. His left hand reaches out for a pair of compass that is rested on a red sphere, surrounded with a yellowish orange aura. Using the high resolution capability of focused ion beam writing, we are able to transform William Blake’s piece of classical art into an image consisting of finely tuned nanocrystals, which we call ‘quantum art’.
