|Abstract: The march towards solid-state lighting as a replacement for fluorescent and incandescent bulbs drove an immense, global research effort to develop efficient, high-brightness, GaN-based blue LEDs. Comparatively, not much is known or discussed about their cousin, the red LED. I will present some of our research on materials for GaAs-based red LEDs. |
Bio: Stephen Farrell received his Bachelor of Science degree in Electrical Engineering from Iowa State University and went on to obtain a PhD at the University of Southern California also in Electrical Engineering. Upon graduation, he took a job working on epitaxial growth of nitride-based materials for blue and green LEDs at industry leader Cree Research. Continuing in the field of crystal growth he took a position with Veeco Instruments, a manufacturer of capital equipment for the semiconductor industry, where he has worked on metalorganic chemical vapor deposition of materials for LEDs, lasers, solar cells, pHEMTs, and other devices.
