Positioning of Nanostructures

14.11.2012
<strong>Background</strong><br>

The pre-patterning of a surface to obtain locally arranged nanostructures is usually done by complex patterning techniques like electron beam lithography, focused ion beam etching or ion implantation. These direct surface patterning techniques can cause crystal damage and defects degrading the quality and performance of the nanostructured elements. Other disadvantages are that these techniques only have short-range impact and are incompatible with batch processing.<br><br> <strong>Technology</strong><br> A method for fabricating layer assemblies with locally arranged nano-structures. A buried, selectively modified underlying layer is used to control the growth of nanostructures on the surface by controlling the laterally inhomogeneous strain distribution. This is done using standard lithography, etching and oxidation techniques. <br> <br>

<strong>Benefits</strong><br> <ul> <li>Long-range impact</li> <li>No defects in close vicinity to the nanostructures</li> <li>Use of conventional structuring methods</li> <li>Electrical adressing of single nanostructures</li> <li>Create nanostructures even on unstructured surfaces</li> <li>Compatible to existing devices</li> </ul><br> <strong>IP Rights</strong><br> US Patent will be granted (priority 03/2011)<br> PCT application <br> <br> <strong>Origin</strong><br> Technische Universität Berlin, Germany</p>

Im Focus: Nuclear Pores Captured on Film

Using an ultra fast-scanning atomic force microscope, a team of researchers from the University of Basel has filmed “living” nuclear pore complexes at work for the first time. Nuclear pores are molecular machines that control the traffic entering or exiting the cell nucleus. In their article published in Nature Nanotechnology, the researchers explain how the passage of unwanted molecules is prevented by rapidly moving molecular “tentacles” inside the pore.

Using high-speed AFM, Roderick Lim, Argovia Professor at the Biozentrum and the Swiss Nanoscience Institute of the University of Basel, has not only directly...

Im Focus: 2+1 is Not Always 3 - In the microworld unity is not always strength

If a person pushes a broken-down car alone, there is a certain effect. If another person helps, the result is the sum of their efforts. If two micro-particles are pushing another microparticle, however, the resulting effect may not necessarily be the sum their efforts. A recent study published in Nature Communications, measured this odd effect that scientists call “many body.”

In the microscopic world, where the modern miniaturized machines at the new frontiers of technology operate, as long as we are in the presence of two...

Im Focus: Tiny microbots that can clean up water

Researchers from the Max Planck Institute Stuttgart have developed self-propelled tiny ‘microbots’ that can remove lead or organic pollution from contaminated water.

Working with colleagues in Barcelona and Singapore, Samuel Sánchez’s group used graphene oxide to make their microscale motors, which are able to adsorb lead...

Im Focus: ORNL researchers discover new state of water molecule

Neutron scattering and computational modeling have revealed unique and unexpected behavior of water molecules under extreme confinement that is unmatched by any known gas, liquid or solid states.

In a paper published in Physical Review Letters, researchers at the Department of Energy's Oak Ridge National Laboratory describe a new tunneling state of...

Im Focus: Bionic Lightweight Design researchers of the Alfred Wegener Institute at Hannover Messe 2016

Honeycomb structures as the basic building block for industrial applications presented using holo pyramid

Researchers of the Alfred Wegener Institute (AWI) will introduce their latest developments in the field of bionic lightweight design at Hannover Messe from 25...
