Exam: Written test; Compulsory oral exam;

The exam includes a written test focused on the topics of the course: - two essay questions on scattering theory and Boltzmann transport equation - one essay question on the empirical pseudopotential method - one essay question on the introduction of quantum transport - two essay questions on organic semiconductors. A complete list of the questions will be provided to the students during the course. The written exam is a closed-book test (no use of any course material is allowed) and has a duration of 90 minutes. During the course, students are requested to submit two reports: a presentation of the results obtained in the MC laboratory, and a presentation of the results obtained in the assigned laboratory (EPM or QT). The objective of the oral test is to assess the capability of the student to explain the numerical results in the submitted presentations. Percentage-type breakdown of the course grades: - Completeness/correctness of the written test (40%) - Quality of the MC report and ability of the student to discuss her/his approach to the numerical laboratories during the oral discussion (40%) - Quality of the EPM/QT reports and ability of the student to discuss her/his approach to the numerical laboratories during the oral discussion (20%).

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
