Solid state physics/Electronic devices (Electronic devices)

The course is taught in English. Aim of the course (1st semester, 1st year) is to provide the theoretical basics of solid state physics and their applications to solid state electronic devices, with particular emphasis in applications in the area of ICTs and energy. This course plays a central role in the development of an Engineer expert in Nanotechnologies, because it extensively provides the basic elements for the understanding of subsequent courses of the MSc learning program. The integrated course is divided in two sections. In the Solid State Physics section the students are organized into two teams for the initial 4 ECTS. The first team is composed of students with a low background in the areas of quantum mechanics and statistics, which have to be learned in order to understand ensuing subjects in physics of matter and electronic devices. The second team is composed of students with an adequate background of modern physics. In both cases the students get (up to different levels of in-depth analysis) the fundamentals of solid state physics functional to study electronic properties of nanostructured materials. The second part of the first section (taught to all students) general methods for the evaluation of the band structure of conducting/semiconducting solids are given. In the Electronic Devices section, the students learn the basics for understanding the physics and the design of electronic devices.

Besides theoretical lectures, the course includes class practices and numerical labs. Class practices propose problems to be solved with analytical techniques (with the possible use of student’s scientific calculator), whereas numerical labs propose group-work sessions dealing with problems to be solved with numerical techniques (with the use of student’s personal computer). These include either more advanced models for a particular class of devices, or the use of numerical fitting techniques to apply analytical models to the analysis of experimental data of real devices. Students are requested to prepare (one per group) a report on 2 numerical labs covering one topic of the first module and one topic of the second module. In each week further exercises are proposed for individual study (homework), whose discussion and solution are provided in the following week.

The Solid State Physics exam consists of a written test aiming at addressing the degree of understanding achieved by the students on the subjects explained during the lectures (see expected learning outcome above). No supporting material is allowed during the exam. The exam aims at assessing the comprehension of the physics of the nanostructures addressed during the lectures and to discuss the application of these nanostructures in innovative electronic devices. When writing the exam sheet the student has to show that he/she is able to rigorously discuss and present the physical models used to describe nanostructure behaviour, highlighting the approximations behind each model. The written test includes multiple-answer questions and statements (to be assessed as true or false) and two open questions on all the course’s subjects. The maximum mark of questions/statements is 12/30, that of open questions is 16/30. The total allotted time is 60 min. The final mark can be increased/decrease up to 3 points on the basis of the quality of the reports on the informatics practices. The written test is passed with a score of at least 18/30. The final score will be obtained by averaging with the score obtained for the Electrons Devices part of the course.

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.
