Lots of great stuff in this video:
-- They get the charge carrier thing right: contrary to many presentations, holes don't really move in a semiconductor. Electrons move to fill holes, making it appear that the holes are moving.
-- Interesting that Nakamura was so willing to defy company orders for so long.
-- The description of the discipline that powered his inventiveness is inspiring.
-- The way he was treated (badly) in Florida because he lacked a PhD is sadly illuminating.
-- The discussion of corporate infighting is interesting.
We wrote about Nakamura before: https://soldersmoke.blogspot.com/2021/02/shuji-nakamura-inventor-of-juliano-blue.html
Derek Muller's Veritasium channel has done some excellent videos! The video's animated semiconductor band graphs are much easier to relate to than our old textbook versions.
ReplyDeleteTrue: holes are not real physical particles, but they exhibit different properties from electrons that give us real problems, such as lower mobility. That can make p-type devices slower.
Nakamura's efforts will likely pay off in areas other than optoelectronics. GaN's FET applications for example.
