OVERVIEW

The course will introduce in the basic concepts of Surface Science and of the nanostructuring at surfaces handling both theory and experimental methods. Laboratory demonstrations will allow the students to better understand the experimental methods and the basic concepts.

AIMS AND CONTENT

LEARNING OUTCOMES

Understanding the fundamentals of surface science and the physical and chemical properties of surfaces and of nanosized objects grown at surfaces. Capacity of reading scientific papers in surface science and applied surface science

AIMS AND LEARNING OUTCOMES

Teaching methods

Frontal Lectures (42 hours) and Laboratory Demonstrations (10 hours)

LESSONS START

in the first semester according to academic calender year

EXAMS

Exam description

The students will be examined orally. They will expose a topic of their choice. The commission will then ask to expose a different topic. Questions will be posed by the jury to assess the knowledge level of the student

Assessment methods

The students will be examined orally. They will expose a topic of their choice. The commission will then ask to expose a different topic. Questions will be posed by the jury to assess the knowledge level of basic concepts by the student. Sufficiency will be reached when the topics are exposed with proper language and the students demonstrates to have a basic understanding of the concepts assocaited to surface science.
