Semiconductor Optoelectronics: Physics and Technology

Legal issue: The book is illegal to sell out of India but I was surprised to buy it from Amazon Germany. the illegal declaration at the front cover was stickered to make it invisible.Cheap: If you are an undergrad student, you may buy it as it is a cheap option and possibly just to understand basic things.Not for grad students: Even though cheap, I don't recommend it for graduate or Ph.D. students to buy this book from this seller.Photocopy with poor paper quality: The book was just a photocopy with paperback binding.Illegible figures: You can not see any figure critically with multiple colors as it is a completely black-and-white photocopy on thin normal paper. You can not use the highlighter as it will be visible on the other page.I wish to submit a negative review.

quite a good book for the people especially who would like to take some research in the exact field in optoelectronics
