84534 - Laboratory of Condensed Matter Physics

Learning outcomes

At the end of the course the student will acquires basic skills to critically elaborate and interpret experimental data. He/she will be able to design a complete experimental apparatus necessary to implement advanced condensed matter physics experiments. The sound hands-on laboratory training will allow the student to achieve advanced capabilities in equipment handling and experimental problem solving.

Course contents

Introduction to radiation-matter interaction processes (UV-Vis-IR, X-rays and charged particles).

Growth techniques for bulk (LEC, HB) and thin film (MBE, CD) advanced materials.

Vacuum physics and technology. Cryogenics (liquid N and He)

Phsyics of sensors: figures of merit and operation principles

Photonic (UV-Vis-IR and X-rays) and charged particle beams (electrons and ions) sources and detectors. Monochromators and spectroscopy apparatuses.

Design and implementation of complex experimental apparatuses.

Laboratory experiments:

1 - X-ray absorption and diffraction

2 – Optoelectronic spectroscopies of semiconductors

3 – Resistivity variation as function of temperature

4 - Fabrication of thin film photodetectors

Readings/Bibliography

Handout of the lecture notes (available on the IoL website for enrolled students)

Teaching methods

Teaching classes and introduction to the experimental apparatuses including hands-on experiences in the laboratories of the Condensed Matter Physics group.

Laboratory experiments in groups of 2-3 people, in the dedicated Condensed Matter Physics educational laboratory (located at the DIFA, viale Berti Pichat 6/2)

An educational trip is organized every year aiming to introduce the students to the different aspect of research in Condensed Matter Physics (large scale facilities, Synchrotron light laboratories, Industrial R&D sector, Research Centres)

As concerns the teaching methods of this course unit, all students must attend Module 1, 2 [https://www.unibo.it/en/services-and-opportunities/health-and-assistance/health-and-safety/online-course-on-health-and-safety-in-study-and-internship-areas] online, while Module 3 on health and safety is to be attended in class. Information about Module 3 attendance schedule is available on the website of your degree programme

Assessment methods

Oral interview, with discussion of the written reports on laboratory experiences (to be handed in at least 15 days before the exam date). The oral interview aims at assessing the acquired knowledge related to the topics discussed during the course. The discussion of the laboratory reports aims at assessing the level of experimental proficiency and the development of critical skills in handling experimental data.

The final mark, on a scale 30/30, takes into account the scores achieved both in the oral interview and in the laboratory reports. the course is passed with a final score equal or greater than 18/30

Final grade grading:

-Preparation on a very limited number of topics covered in the course and analytical ability that emerges only with the help of the teacher, expression in overall correct language → 18-19;

-Preparation on a limited number of topics covered in the course and autonomous analytical ability only on purely executive issues, expression in correct language → 20-24;

-Preparation on a large number of topics covered in the course, ability to make autonomous choices of critical analysis, mastery of specific terminology → 25-29;

-Substantially exhaustive preparation on the topics covered in the course, ability to make autonomous choices of critical analysis and connection, full mastery of specific terminology and ability to argue and self-reflect → 30-30L.

Students with Specific Learning Disabilities (SLD) or temporary/permanent disabilities are advised to contact the University Office responsible in a timely manner (https://site.unibo.it/studenti-con-disabilita-e-dsa/en ). The office will be responsible for proposing any necessary accommodations to the students concerned. These accommodations must be submitted to the instructor for approval at least 15 days in advance, and will be evaluated in light of the learning objectives of the course.

 

Teaching tools

Educational physics laboratory dedicated to experiments of condensed matter physics, with real time data acquisition systems. PCs are available to the students for elaborating data, images, and reports throughout the whole course duration.
