Best ResponseYou've already chosen the best response.0the region between ntype and ptype semiconductor material in a pn junction. i think the positive holes are filled by excess electrons from the ntype material...or something, ha. i could be wrong

Best ResponseYou've already chosen the best response.0This 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.

Best ResponseYou've already chosen the best response.0Laka, 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.

Best ResponseYou've already chosen the best response.0that eight is supposed to be either. lol

Best ResponseYou've already chosen the best response.0wait, bias just refers to the polarity of the voltage, right? ive havent learnt that term yet

Best ResponseYou've already chosen the best response.0bias is the external applied voltage and can be either forward bias or reverse bias depending on the polarity of the externally applied voltage.

Best ResponseYou've already chosen the best response.0so 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

Best ResponseYou've already chosen the best response.0true, 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
