来自DIODE - PN JUNCTION AND METAL SEMICONDUCTOR CONTACT的热门评论
Coursera helped me learn skills to develop my career and enrich my expertise.
The tests are quite hard but it can teach students more effectively.
THE CONCEPTS WERE SIMPLE AND NO COMPLEX TERMINOLOGY IS USED, BUT PROBLEMS IN QUIZ FROM SEEK 3 & 4 ,WERE DIFFICULT TO SOLVE JUST FROM LISTENING TO THE LECTURES.
Lectures are very informative, and the quiz questions truly test the way person reasons and determines solution to given operating conditions for junction contacts.
