the region between n-type and p-type semiconductor material in a p-n junction. i think the positive holes are filled by excess electrons from the n-type material...or something, ha. i could be wrong
This is the small area at the junction of the two different semiconductor materials N and P This region is a electrically charged consisting primarily of ionized atoms with relatively few free electrons or holes.
radar, how does the gap form though?
thanks u very much
Laka, it is a quantum thing with the mobile electrons and holes be caught up in the valence bands ioniizingg the atoms, very similar to a small capacitor where applied bias will eight separate the plates further of bring them closer together depending on the polarity of the bias. the process is by diffusion.
that eight is supposed to be either. lol
wait, bias just refers to the polarity of the voltage, right? ive havent learnt that term yet
nevermind, I googled it :) thanks
bias is the external applied voltage and can be either forward bias or reverse bias depending on the polarity of the externally applied voltage.
so from what i gathered, reverse bias occurs when the holes and free electrons are attracted to opposite ends of the semiconductor material, widening the depletion zone and stopping current flow? whereas forward bias is the opposite? like, there is a two way current flow: conventional current (positive holes) in one direction and an electron drift in the other? is this right
thanks by the way, i zoned out in class when we were getting taught this
It is a good field to get in but is changing very fast. Can'nt keep up lol
I worked in radar with the FAA both as an electronic tech and electronic engineer.
Thankfully I am now retirted and have been retired since 1994
true, it is a fast advancing field. and haha, i was born in 1994. we're doing semiconductors in physics and there are exams next week. but i doubt we have to know this much anyway
Understand, good luck with it.
