Subject fundamentals
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.

Section: Solid State Physics

Class practices include simple problem solving activities, with strict connections to theoretical lectures. In some cases scientific calculators (students' personal property) may be required. In the second part of this Section (joint student teams) the students will learn how to apply the DFT method to practical cases by informatics practices.

Section: Electronic Devices

Class practices include problems to be solved with analytical techniques (with the possible use of studentís scientific calculator) and problems to be solved with numerical techniques (with the use of studentís personal computer). In each week further exercises are proposed for individual study (homework), whose discussion and solution is provided in the following week

Assessment and grading criteria
Section: Solid State Physics.

The exam is written. The test includes multiple-answer questions and statements (to be assessed as true or false) and two open questions on all the courseís subjects. The maximum mark of questions/statements is 20/30, that of open questions is 10/30. The total allotted time is 90 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 15/30. Willing students with an assessed knowledge of solid-state physics may ask for an oral test to possibly increase their marks.

Section: Electronic Devices

Tthe exam is written. It includes numerical exercises and open answer questions and it is aimed at assessing the student ability to analyze the operation of the devices presented during the course. For interested students, with a demonstrated knowledge of elementary semiconductor devices, the written exam may be replaced by a term paper on one of the course topics and an oral exam for discussion of the presented results.

The integrated course is held by three teachers. Two of them are responsible for the solid state physics section (6 ECTS), the third teacher is responsible for the electronic devices section (6 ECTS). The teachers strictly cooperate in establishing the time schedule in order to provide the students with an attractive and coherent teaching program
