In addition to ECE 447 (Active Microwave Circuit Design), Professor Feng will be joint-teaching a course with Professor K.Y. Cheng. This new course will focus on the physical operation and historical applications of LEDs and Solar Cells.
This will be a great opportunity to learn about these two important devices, from two men that worked with some of the most influential inventors in the field of optoelectronic devices.
Course webpage coming soon for ECE 498MF (Semiconductor LEDs and Solar Cells). For now, information can be found on the ECE department summary for the course
