The width of the base is very thin to increase the majority carrier concentration gradient in the base region thereby enhancing the diffusion current and also to reduce the number of majority carriers lost due to recombination in the base.

The emitter, the base, and the collector are parts of a transistor.

The two basic types of transistors are the NPN transistorand the PNP transistor. Certainly there are many other semiconductor devices, but these are arguably the two basic ones.
Base of transistor is made thin just to get Collector current equal to Emitter current.
Emitter is heavily doped because to provide charge carriers to Base & Collector region, Base and Collectors are lightly doped because to accept those charge carriers.

3: emitter, base, collectorThere are three regions but to be absolutely picky I think only two of them need be doped.Nope: they MUST be doped NPN or PNP. If any are undoped it will not function as a transistor.
An emitter is heavily doped in a transistor to increase its conductivity and allow a large number of charge carriers to flow from the emitter to the base, resulting in a low-resistance path for current flow. This helps in achieving high current gain and improving the overall performance of the transistor.
base
In what sense? In transistor jargon, p stands for positively doped type and n for negatively doped semiconductor. Another terminology used in mobile games is Pass 'n play.
Explain why the innerlayer two layers of an scr are lightly doprd and are
hall coefficient of a lightly doped semiconductor will decrease with increase in temp as hall coefficient is inversely proportional to number density of charge carriers.
Its is the emiiter base of the transistor voltage!
Since the base in an n-p-n transistor is kept very thin, very few electrons get to recombine with holes and escape out of base, most of the electrons are injected from emitter into the collector. As a result, Base-current is very small. Whereas the Collector-current is almost equal to the Emitter-current.
NPN and PNP are transistor types. The difference in the way the layers of semiconductor material are doped with impurities.
The emitter, the base, and the collector are parts of a transistor.
