Nanotools

The course deals with characterization and structuring tools with a high (less than 100 nm) spatial resolution, which are relevant for nanotechnology: Focused Ion Beam (FIB), Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM) and Scanning Transmission Electron Microscopy (STEM). The course is split into two main parts: laboratory work and lectures.

The laboratory work involves student active learning via hands-on experience using the FIB-SEM, AFM and STEM. In the first laboratory exercise, the students nanostructure a thin film material in the FIB. This sample is then characterized using the SEM, AFM and STEM. Covering the major data classes: imaging, spectroscopy and diffraction. This also includes nanoscale characterization of electromagnetic fields. Teaching in advanced numerical data analysis using Python and Jupyter Notebooks is included via computer exercises, and use of HPC computation cluster for processing of data. Here, the raw data from the laboratory exercises is processed and visualized. The results from the laboratory work is written up into a project report, utilizing the results from the computer exercises.

The lectures cover the theory behind the aforementioned techniques, and how the techniques can be used to address sustainability challenges. Other nanostructuring and characterization techniques might also be covered. Note that the hands-on laboratory work is subject to equipment availability, so the lab-work might consist of other instruments.

After the course, the student will have both theoretical and hands-on experience with several high-end microscopy techniques. Having learnt how to both structure and characterize materials at nanometer length scales and acquire their own data. This also includes knowledge on how to process the raw data from these instruments using the open source and reproducible software tools Python, Jupyter Notebook and Gwyddion. Experience in the use of Linux-based High Performance Computing cluster. Experience in group-based writing of a scientific style project report.

Hands-on laboratory work at NTNU Nanolab and NORTEM lab, lectures, and computer exercises. The laboratory work is done in lab groups consisting of a minimum of 2 students, which also write the project report together. Laboratory and computer exercise must be approved to be admitted to the exam. Expected workload in the course is 225 hours.

To be able to do the compulsory laboratory work, you must have completed NTNU NanoLab's clean room course. If you are taking TFY4330 Nanotools, you can complete this clean room course before the start of the semester: send an email to nanolab@ntnu.no, and write that you are taking the course TFY4330 Nanotools. This clean room course can also be completed after the start of the semester.
