Due to technology advancement, optoelectronics has become an essential part of our lives. The sector of semiconductor optoelectronics generally deals with the physics and technology of semiconductor optoelectronic devices, for example, light emitting diodes, laser diodes and photodiodes.

In this [course_title], you will learn the essentials of semiconductor physics, including the interaction of photons with electrons and holes in a semiconductor. Furthermore, the fundamentals of optical inter-band transitions also included in this course.


This course does not involve any written exams. Students need to answer 5 assignment questions to complete the course, the answers will be in the form of written work in pdf or word. Students can write the answers in their own time. Each answer needs to be 200 words (1 Page). Once the answers are submitted, the tutor will check and assess the work.


Edukite courses are free to study. To successfully complete a course you must submit all the assignment of the course as part of the assessment. Upon successful completion of a course, you can choose to make your achievement formal by obtaining your Certificate at a cost of £49.

Having an Official Edukite Certification is a great way to celebrate and share your success. You can:

  • Add the certificate to your CV or resume and brighten up your career
