SURFACE PHYSICS AND NANOSTRUCTURES

Course objectives

GENERAL OBJECTIVES: The Surface Physics and Nanostructures course aims to provide the knowledge of the structural properties of solid systems at low dimensional scale and to understand their characteristics from the point of view of both electronic and vibrational degrees of freedom. The optical properties of nanostructured semiconductor systems and magnetic properties of nanostructured metal systems will then be analyzed. At the end of the course, students will be able to transpose the knowledge of 3D solid state physics to two-dimensional and one-dimensional systems and have an in-depth knowledge of the frontier topics in nanosciences. These acquisitions will be verified also thanks to the presentation of the topics in seminars held by the students. SPECIFIC OBJECTIVES: A - Knowledge and understanding OF 1) To know the properties of low-dimensional solid systems OF 2) To understand the effects of reduced dimensionality OF 3) To know the most advanced techniques for studying the low-dimensional systems B - Application skills OF 4) To be able to deduce the properties of a surface or a nanostructure OF 5) To be able to choose the correct technqiue to investigate a surface or a nanostructure C - Autonomy of judgment OF 6) To be able to autonomously individuate an experiment on low-dimensional systems OF 7) To be able to integrate the acquired knowledge so to be able to face a scientific problem associated to low-dimensional systems D - Communication skills OF 8) To know how to communicate the properties of a low-dimensional system OF 9) To be able to communicate the advantages of an advanced investigation E - Ability to learn OF 10) To have the ability to consult the specific scientific literature OF 11) To be able to evaluate the specific scientific literature OF 12) To be able to design and plan an experiment on low dimensional systems

Course program
From surfaces to new atomic and molecular architectures - 1D and 2D as compared to 3D systems - Low-dimensional crystalline structures – Symmetries and symmetry operations – Surface thermodynamics - Relaxation and reconstruction processes, phase transitions in the formation of surfaces - Structural properties and techniques (AFM, STM, LEED, GIXD) - Free electron gas in 1D and 2D - Electronic properties (electron gas, band structure) of nanostructures - Elementary excitations in 2D systems (phonons, plasmons, etc.) - Magnetic nanostructures, the giant magnetoresistance - Electron spectroscopic techniques (angular-resolved photoelectron spectroscopy, ...) - Electronic properties and structure of nanostructures: etherostructures, nano-wires, self-assembled monolayers – Graphene: electronic states, structure, supported graphene, growth, characterization, doping, ...).
Prerequisites
Basic knowledge of Condensed Matter Physics and Solis State Physics. The lectures are suited for students following the curriculum in Condensed Matter Physics, but basic knowledge of Condensed Matter Physics is enough also for student following the other curricula.
Books
- scientific papers concerning the specific experimental techniques of the laboratory - notes available on the web site: https://elearning.uniroma1.it/course/view.php?id=13562
Teaching mode
Lectures, seminars of experts of state of the art of the research on nanostructures. Seminars organised by the students and discussion.
Frequency
Attendance to the lectures is not mandatory but strongly recommended.
Exam mode
Short talk (30') on scientific issues about nanostructures, with discussion on the syllabus and given lectures The examination consists of a short talk and an interview on the most relevant topics presented in the course. To pass the exam, the student must be able to present arguments discussed and explained during the course. The student will be asked to apply the methods learned during the course and situations similar to those that were discussed in the course. The evaluation takes into account: - Correctness and completeness of the concepts discussed by the student; - clarity and rigor of presentation; - knowledge of the recent literature on the chosen issues of the short talk. Students who demonstrate to know all the basic arguments exposed in the syllabus will be scored with 18/30; students who answer in a good way to the questions and are able to propose a solution to the queries will be scored up to 24/30; students who answer in a very good way to the questions and can precisely describe the solutions of the queries will be scored up to 27/30; students who demonstrate a full knowledge of the syllabus, with an exact solution of all the queries, with inference ability and also showing a critical approach, will be evaluated up to 30/30 cum laude.
