The course was more than enough to provide introductory information to semiconductor physics. Even though the video lectures are well prepared, they do not include sufficient information to deal with some of the problems in the assignment and homework quizzes. I am aware that it is not possible to add that much information to the videos. However, there can ( and must) be a complimentary reading list and/or names of various course books.

The lectures (videos) were great, but the assignments required information NOT presented in lecture. There were also multiple cases where the assignment questions required assumptions not stated in the problem to solve properly. To improve the course, it would be good to go back through the assignments and evaluate whether or not the learner is setup for success from this course on its own.

Great lecture but very little help provided for Quiz & Homework

The course was very good and informative. Assignments was very tough for which we worked out a lot

It was good .

But the course was not very interactive because there were a few videos and after that an assignment and a long list of problems which could have been broken into parts for the better .Also if you were stuck in a problem for a while there were no hints or resources to refer to . Also refiiling the same answers for 16 questions was very annoying just because you had to a change a single answer .

I found the material very interesting and very thankful for the instructor, university and coursera for this opportunity to learn. However it would have a much better experience if the following were improved:

- The course, unfortunately, appears orphaned. There is little involvement from actual instructor or TAs. Forums have automated posts from the instructor, but little actual content. Posts from other students are mostly spam (with a few exceptions that are far between).

- Peer graded assignments did not get any actionable feedback from graders (other peers). This makes it hard to see mistakes. Unfortunately in some cases the best way to pass is to just resubmit exact same work and have a different set of eyes look at it. Moreover there is a ridiculous amount of junk submissions from other peers (random screenshots, random PDFs, excel sheets etc).

- I found instructor's material delivery hard to follow at times - mostly there would be some assumptions that they state with no explanation.

- Assignments have some obvious errors and typos. Given that this course has been around since 2017, I would have expected those to be ironed out by now (2022). This supports the point about this course being orphaned.

- Lecture material does not cover enough for solving some of the assignments. In a way this is OK and encourages additional research, however it would help to make this more explicit that this material is not covered and we are expected to read up.

The lectures could be in more detail. The assignments are very high level compared to the lectures. It was more of a self-study.

A very useful course for me to understand semiconductor physics. And systematically operated course.

Very informative course and nice approach to solve problems. Well tailored course suited to under graduate engineering students

Good course in general. Some explanations were too short for me, but maybe I am just lagging some previous knowledge. The homework problem descriptions are sometimes incomplete or not fully clear. Anyway, the fundamentals of semiconductors are explained in depth and I learned a lot from the course, so four stars.

Using forms to answer problems with equations is not a good idea. It will be hard for users to input and match the right answers.

The course is interesting and well planned, but one needs to have basic idea of the topics before getting into the course. The assignment and homework problems are very random ,sometimes its tough and sometimes it is too easy.

Overall it is a nice course, I recommend it to everyone who is interested.

There are unnecessary numericals , also no solved examples, neither any particular reading provided for extra learning for more explanation.

This is quite an interesting course, as it supplemented my university courses. The content were same, so got time to brush up the concepts. Elementary knowledge of Quantum Mechanics is though not needed, but helps. However, the quizzes are little tough and passing rate is quite high. No hints or solved examples available before taking any quiz.

I learned a lot , being it my first core subject and professor Wounjhang Park explanations were flawless and the short tutorial's were amazing , short yet informative and someone like me who's new to this topic understood the basics pretty easily.

THAN-YOU , TO COURSERA & AND A RESPECTED BOW TO PROFESSOR Wounjhang Park.

I am very happy to be a part of course era learner group. I am benefited by doing this course and learnt the topic in detail even though it is known to me. Problems given the assignment are very tough and to solve these I done hard work from which I learnt the subject in depth.

Amazing course!! Teacher is fantastic; makes every semiconductor concept simple to comprehend. This course has been very helpful and I am grateful that I found this course because it helped me eliminate the fear of semiconductor physics and quantum mechanics!

The is Grate course.

The lattice part at the beginning is not all that well connected to what follows. I would enter the band structure without lattice discussion.

This is an interesting course to study, it might take a long time to understand concepts to build mathematical equations and solve them. Challenging course

This was excellent course to go through basics of semiconductor physics, structured with well specified videos and homework. Thank you a lot.
