Lecturers: Dr. Szabolcs Csonka, Dr. Sándor Bordács (Dep. of Physics), Dr. Gábor Dobos (Dep. of Atomic Physics)

Requirements: 3/0/0/v/4

Language: English

Mark: based on oral exam

Consultation: based on private communication

Time and place: Wednesday 9:30, MS Teams Online platform: Nanotechnology and Material Science

 

 

Structure and rules of the online lectures:

• For each lecture there will be a video, which you should listen.  Then a short test will be available online, which should be filled till next week. Its role is to give feedback how deeply you understand the content. Next week we will have  a discussion section from the same topic along the questions of the test, where I expect an interactive discussion. Then new video will be available with the new topic.
• The videos and slides you will find in the files and videos menu of Teams and at the homepage.
• In order to protect the voice quality and avoid slow down please enter the meeting of the online course with microphone and camera switched off.
• The important part will be recorded on videos, other recording is forbidden.
• Please use the chat window, if you have questions, observe some problems. There is a separate channel to each Lecture, please comment there.

Exam

There will be an oral exam.
It starts with an entrance part: a short test from the questions contained in the tests during the lecture.
Then one of the Topics (see webpage of the course) should be explained in detail after a preparation period. Lecture notes can be used during the preparation.  Then short prompt questions come from all other topics, here lecture notes cannot  be used. 
During the exam it is obligatory to use your web camera. At the beginning you should show your student card. In the evaluation the understanding of the topics and the underlying physical mechanisms are the important.
