Why going to nano ?

The ebeam lithography can combine top/down and bottom/up approaches to further reduce the dimension of our devices. We take advantage of the new dominant physical mechanisms to elaborate novel materials with extended functionalities. Starting either from thin films and heterostructures or from smaller building blocks (nanoparticles, nanowires), we can fabricate different devices and measurements environnements.

 

 

 

 

 

 

 

Nanowires are model objects in such concern. They are the basic electrical circuitry. Their physical properties are governed by the interplay between their dimension and the typical length scales of magnetism and electronic transport. Magnetization reversal, magneto-transport, action of magnetization on the current but also action of the current on the magnetization are some examples of the novel properties existing at the bottom.

Moreover nanowires offer new opportunities in nanotechnologies. They are not only the subject of basic research but also novel tolls for the characterization of nano-objects. They can also be integrated in systems taking advantages of their reduced dimension and high aspect ratio. For instance they are efficient field gradient sources in magnetic force and magnetic resonance force microscopies, and efficient field emission electronic sources.
