Verification of learning

The student evaluation consists of an oral exam composed by two parts:
a) a short seminar, 10-minute long at most, about an argument or a device studied in the course, freely chosen by the student, concerning the themes treated in class, or even not treated, but still inherent to nanoelectronics
b) a short colloquium, 15/20 minute long, concerning the arguments of the class
The student must demonstrate
i) to be able of clearly and strictly connecting to the quantum mechanical principles to the description of the basic operation principles of nanoelectronic devices
ii) to identify the limits and the potentialities of the nanoelectronic devices based on the physical principles related to the electronic wave function control.
The exam test score by a vote of thirty.
The exam evaluation takes into account the following elements:
1) the ability to identify the quantum effects in the description of a device operation, and the knowledge of the basic laws of quantum mechanics
3) the use of a suitable language
To pass the exam, so bring a vote of no less than 18/30, the student must demonstrate to have acquired a sufficient knowledge of the properties of the building blocks for nano-scale electronic devices, a basic understanding of the devices based on quantum phenomena and must demonstrate the ability to properly connect the laws of quantum mechanics with the properties of nanoscale devices.
To achieve a score of 30/30, students must demonstrate that they have acquired an excellent knowledge of all the topics covered during the course
