Our laboratory is equipped with experimental facilities dedicated to the elaboration of nanostructures as well as to their optical characterization. For any supplemental information about these facilities, please contact Eloïse Devaux (

Sample preparation

  • Chemistry room equipped with facilities for substrates cleaning and samples preparation (sonicator, oven, ozone cleaner, spin-coater, etc…)
  • Egun evaporator Plassys (ME300) with four crucibles (generally loaded with Au, Ag, Cr and Al). Heating system on the substrate holder ( for a 3″ diameter substrate or four 2″ susbstrates)
  • Metal magnetron sputterer Plassys (MP300) with two targets (generally Ag and Al). Cooling system on the susbrate holder (for a single 2″ substrate)
  • Dielectric RF sputterer Plassys (MS300) with two targets (generally SiO2, Al2O3, Si, TiO2, etc… ) (for a single 2″ substrate)
  • Metal magnetron “table-top” sputterer Quorumtech (K575X) with two targets (generally Au and Ag) (for four 2″ substrates)

For characterization of the morphology of the samples, we have access to a profilmeter and an AFM in Samori’s group, and to the SEM of the institute (Quanta FEG 250 from FEI company, equipped with EDX and working in ESEM). But we have also our own FIB/SEM system described here below.

Sample fabrication

We have our own FIB/SEM system (Focused Ion Beam and Scanning Electron Microscope). It is a cross-beam Auriga from Zeiss company (acquired in 2013). FIB allows the direct milling of any material with a high resolution (below 10nm), as well as the ion-induced deposition/etching of materials. SEM, in addition to be a powerful tool for sample characterization, allow us to extend our toolbox for doing nanostructures by e-beam lithography. In addition, the system is fully equipped with options allowing a wide range of tasks :

  • Single GIS (Gas Injection System) for Pt deposition
  • Multi-GIS for Au,W,SiOx deposition and XeF2 and Water for gas assisted etching of respectively Si based and Carbon based materials
  • EDX detector for qualitative and semi-quantitative analysis
  • BSD detector for collection of back-scattered electrons for analysis
  • Charge-compensation system to do SEM imaging of non-conductive materials
  • Flood Gun to do FIB milling of non-conductive materials
  • Fast Beam Blanker for e-beam lithography

But for those who are more micro than nano, we have also access to the Laser Writer of Samori’s group, or to the mask aligner of ISIS, located in the clean room, allowing to create structures from 1µm to many mm size.
