Advanced Instrumentation for Ion Nano-Analytics

The "Advanced Instrumentation for Ion Nano-Analytics" (AINA) group focuses on the development of scientific instruments based on charged particle beams and correlative workflows taking advantage of these instruments. The group’s R&D activity covers fundamental investigations, instrument development and application development. The targeted fields of application of the instrumentation and methodologies developed by AINA are:

  • nano-imaging
  • nano-analysis
  • in-situ process control for nano-fabrication.

Our research activities are performed in cooperation with leading international instrument manufacturers and with research groups specialized in the relevant fields.

Main expertise fields

  • Nano-analytics
  • Charged particle optics
  • Ion-matter and laser-ion interactions
  • Instrument development and prototyping (including mechanics, electronics, software development)

Research challenges

The development of innovative characterization tools is of paramount importance to advance the frontiers of materials science. Due to the ever-increasing complexity of devices and continuously shrinking geometries in materials science and engineering, the characterization tools and techniques are facing new challenges and need to anticipate future trends:

  • The development of new hardware to improve following aspects of nano-analytics:
                - Lateral resolution
                - Sensitivity
                - Throughput
                - Automation
  • The development of correlative workflows to maximize information by combining results from different, complementary techniques
  • The development of new algorithms and software to deal with the increasing complexity of data and to prepare for automation of data treatment
  • The aforementioned developments need to be applicable to the fields of:
                - materials science
                - life sciences
