Let's explore how LEDs - light-emitting diodes - work and their advantages over traditional light bulbs.
Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere. We offer quizzes, questions, instructional videos, and articles on a range of academic subjects, including math, biology, chemistry, physics, history, economics, finance, grammar, preschool learning, and more. We provide teachers with tools and data so they can help their students develop the skills, habits, and mindsets for success in school and beyond. Khan Academy has been translated into dozens of languages, and 15 million people around the globe learn on Khan Academy every month. As a 501(c)(3) nonprofit organization, we would love your help!

Very, Very well done.(Wish you could pre-write the words to lessen my anxiety level.) I think that there will Always be heat generation, even in recombination, albeit sooo tiny. And a pn junction is not a diode (and vice-versa) it only contains it as do transistors, scr, jfets, ect... Enough of my criticism. Do leds use a specific substrate instead of silicon?

LED is heavily doped semiconductor. So there is excess of minority charge carreirs, so they recombine more often than normal diodes

If recombination takes place in forward bias why do its depletion region decrease instead of increses
@hkkapoor5703
@hkkapoor5703 2 роки тому
Hii As I read , when ele. and holes recombine at that time a EHP generate in p side and ele move towards +ve terminal (p side) and hole move (fulfill near by electron ) towards -ve terminal and such more and more charge carriers generates in forward bias .
