Learning Outcomes

The course will give the student an understanding of the different kinds of elastic properties of solid materials, and the methods used in describing these in laws of nature. The student will understand the relationship between elasticity and temperature, and knows how to calculate the amount of thermal stress in a given structure. During the course, the student learns how to mathematically model harmonic oscillations of an ideal spring-block system, as well as mechanical wave motion produced by a combination of such oscillators. The knowledge is applied to modelling electromagntic wave motion. In the latter part of the course, the student will learn the microscopic stucture of matter, Bohr’s atomic model and the relationship between the energy levels of an atom and the spectral lines emitted by the atom. The atomic model is applied in describing semiconducting materials and in learning the most important properties of p and n type semiconductors. A special attention is paid in looking at the combinations of the different types of semiconductors (diodes, transistors), and the student will learn the importance of these to modern semiconductor technology. At the end of the course, the student will learn the principle of the most common applications of atomic physics and semiconductors. In parallel with the theoretical studies, the student will carry out experimental work in laboratory environment. The results are analysed and reports are written, including full error calculations.

The total amount of student's work is 81 h, which contains 42 h of contact studies.

Mode of Delivery / Planned Learning Activities and Teaching Methods

The relevant theories of physics, together with associated problems and applications, are studied on a course of lectures. In addition, the student will individually solve a number of given homework exercises. Students will also take part in laboratory measurements. The measurements are done in groups of 3 students.

Assessment Criteria

Grade 1: The student knows those subjects of the course, which are necessary for the forthcoming studies and working life.
Grade 3: The student is well-abled to utilize the course contents.
Grade 5: The student is able to apply creatively the contents of the course.

Assessment Methods

The assessment is based on examinations, homework exercises and laboratory work. A student must solve at least 25 % of the given homework exercises, and (s)he must take part in all the associated experiments in the laboratory of Physics, as well as write acceptably two reports on the measurements.
