Description
Areas of activity :
The AFM (Near Field Microscopy) platform is dedicated to the imaging and characterisation of materials and nanostructures at the nanoscale. Near-field microscopy responds to the growing need for IS2M’s various research areas to add a 3-dimensional observation tool. In this way, it complements other conventional microscopy techniques to monitor their technology on an ever smaller scale.
In addition, it provides the opportunity to characterise at physical (electrical, mechanical, magnetic …) and chemical behaviour of new materials or components at the nanoscale.
Main equipment (strengths of the Institute) :
IS2M’s near-field microscopy platform is equipped with :
- 3 atomic force microscopes (AFM) :
- NanoScope IV
- NanoScope V
- FlexAFM
- 1 Tunnel Effect Microscope
The four AFM sets are complementary : they cover a wide range of sample sizes and access various environmental conditions (neutral gas, controlled humidity, liquid medium, variable temperature from -40°C to 350°C). Two of the systems also make it possible to work in STM.
