UHV system 2: Inverse Photoemission Spectroscopy (IPES)

UHV system 3: Atomic Force Microscopy (AFM)

AFM-Raman

·       UHV system 1: Scanning Tunneling Microscopy (STM) and Photoemission (XPS/UPS)

Omicron VT-STM + Omicron EA125 electron analyzer + UV/X-ray sources
UHV environment, variable temperature (100-400K)
Combined apparatus equipped with LEED and XPS/UPS
Full control on the sample temperature during preparation and transfer thanks to a flux-cryostat manipulator (100-1000K)

·       UHV system 3: Atomic Force Microscopy (AFM)

This UHV setup was built in April 2008 and is operational since December 2008. It consists of two inter-connected UHV chambers. The “preparation” chamber (P-chamber) includes:
  • two built-in molecular evaporators facing quartz micro-balances
  • a heating stage allowing for the electron bombardment (up to 1500°C )
  • an additional heating stage for temperatures up to 600°C
  • an ion gun
  The “analysis” chamber (A-chamber) includes:
  • the VT-AFM from Omicron®
  • a low current LEED-Auger Electrons spectroscopy setup from OCI MicroEngineering®
The driving electronics of the VT-AFM was purchased form RHK (SPM1000). It includes an external preamplifier with 3MHz bandwidth, a Mathbox for conditioning the signals of the PSD, the PLLPro AFM Control System, a Piezo Motor Control unit for driving the macroscopic displacements of the sample, and the SPM100 unit for driving the piezos. The RHK PLLPro2, with ultra-high performance and Kelvin Probe capability, will be delivered soon.

·       AFM-Raman  

L’IM2NP possède 2 équipements de caractérisation physico-chimique en sciences des matériaux : un spectromètre Raman et un microscope à force atomique. Cet ensemble forme un outil de caractérisation unique et particulièrement performant en région PACA.   Ces deux appareils fournissent des informations parfaitement complémentaires et sont susceptibles d’intéresser la communauté matériau dans son ensemble, de la microélectronique à l’environnement.   A terme ces deux équipements seront couplés optiquement pour réaliser des mesures de diffusion Raman à résolution nanométrique : c’est le nanoRaman.
