GENERAL INFORMATION ON THE COURSE 2

In this course the students will learn how to use some techniques and some instruments currently used in the research laboratories. The students will perform experiments on subjects where some quantum mechanics effects in solid state physics are particularly evident and/or subject related to nanostructures. They will be free within some limits to organize the experiments, put their hands on the instruments, modify the set-up, analyze the data, and, obviously, make mistakes. They will also characterize and optimize the instruments used and analyze the noise present and its origin. I hope the students will learn that (in a laboratory) they cannot take anything for granted and that they can learn a lot from mistakes.

Possible topics are
1) Quantum confinement effects in quantum wells in semiconductors studied by photoluminescence
2) Quantization of the conductance of nanowires studied by STM (scanning tunneling microscopy) (not in 2022)

ORGANIZATION OF THE COURSE:

If students of an internationalization program attend the course the lessons are in English.
The students have to do 72 hours of activity in the laboratories. They will form groups of 3-5 people. The labs will be available in the afternoons, approximately from 14.00 to 19.30.
Each group will go to the lab about 1.3 times a week on the average.  Different schedules are possible.
After the first lessons, after the description of the course by the teacher, and the questions by the students, the students will define the groups.
It is important to have the name of the students as soon as possible, in order to complete some bureaucratic formalities if they will work in labs outside the university. Please send the names to modesti@ts.infn.it   The labs are in room "laboratorio di fisica II" in the basement of building C1 or at TASC-INFM, and at Elettra, both at the Research Area, Basovizza.

The first lessons will take approximately 2- 2.5 weeks. The lab activity will start in the third week approximately.

The students are strongly recommended to analyze the data taken in a lab session before the beginning of the following laboratory session and to discuss them with the teacher as soon as possible.

EXAMS
The groups of students have to present a report on their experiments at the end of the course before the oral examinations. The oral examination will be on the techniques used by the students, on the data acquisition and data analysis, on the instruments used, on the noise present in the data, on the meaning of the obtained results.
