Prerequisites

Basic knowledge in physics and chemistry.


Objectives and Contextualisation

Acquire the knowledge needed to understand the fundamentals and advances capabilities of the different Scanning Probe Microscopes (SPM) relevant for Nanoscience and Nanotechnology.


Competences

  • Communicate and justify conclusions clearly and unambiguously to both specialised and non-specialised audiences.
  • Continue the learning process, to a large extent autonomously
  • Identify the characterisation and analysis techniques typically adopted in nanotechnology and know the principles behind these, within one's specialisation.
  • Show expertise in using scientific terminology and explaining research results in the context of scientific production, in order to understand and interact effectively with other professionals.
  • Solve problems in new or little-known situations within broader (or multidisciplinary) contexts related to the field of study.

Learning Outcomes

  1. Assess the particularities of physical and chemical processes that take place on surfaces.
  2. Communicate and justify conclusions clearly and unambiguously to both specialised and non-specialised audiences.
  3. Continue the learning process, to a large extent autonomously
  4. Critically analyse the validity of results obtained using SPMs.
  5. Know the appropriate local probe microscopy variant for the property to be studied.
  6. Show expertise in using scientific terminology and explaining research results in the context of scientific production, in order to understand and interact effectively with other professionals.
  7. Solve problems in new or little-known situations within broader (or multidisciplinary) contexts related to the field of study.
  8. Use the atomic force microscope in its basic modes.

Assessment

Continous Assessment Activities

Title Weighting Hours ECTS Learning Outcomes
Oral presentations 50 % 0 0 2, 3, 6
Participation 10% 0 0 4, 5, 7, 8
Written report 40 % 0 0 1, 3, 5, 6, 7

At the end of the course the student must deliver a written report (10 pages) and do a 5 minutes oral presentation. Participation in lectures and laboratory workshop will be also taken into account for the final score.
