    7. Objectives, learning outcomes and obtained knowledge The primary objective of the Materials in Electronics course is to provide students with the basic knowledge of materials structure and materials technology required for electrical engineers. This includes the study of different material models, basic crystallography, and an understanding of the fundamental physical properties and consequent behavior of the main conducting, semiconducting, insulating, magnetic and optical materials used in electrical engineering practice. The course also aims to introduce the changes in material properties resulting from geometric scaling (size reduction) and the more important quantum mechanical phenomena that underlie the operation of modern micro- and nanoelectronic devices.
    8. Synopsis

    1. Introduction - outline of the topic and requirements. Structure of materials according to a bottom-up model. Bohr and quantum mechanical atomic models. Electrons and atomic orbitals, interpretation of quantum numbers. Pauli's principle.

    14. Modern material systems: nanomaterials and their applications (nanosensors, nanopackaging, nanometrology).

    9. Method of instruction Lectures.
    10. Assessment During the semester, two 60-min mid-term tests should be written and passed.
    11. Recaps The mid-term test can be retaken during the supplementary week. A second retake possibility will only be held, if the success rate of previous tests is below 30% (as per regulations).
    12. Consultations Before the mid-term tests, as agreed upon with the lecturers.
    13. References, textbooks and resources E-learning materials developed by the department.

    IMSc program

    -For IMSc students extra materials will be provided to study.

    -At the mid-term tests extra questions can be answered to collect IMSc points.

    IMSc score At the mid-term tests extra questions can be answered to collect IMSc points. A total of 10 IMSc points can be collected in the two tests (5-5 points). The ratio of IMSc questions in the tests is 25%, IMSc points can be collected only if the test is above 75%. Students not enrolled in the program can also collect these points.
