Question
There are several elements that we regard as semiconductors. The common property of these elements is that they have
electrons, which are randomly organized about the nucleus.
no electrons beyond a closed shell.
four outer electrons beyond a closed shell.
outer electrons which cannot move.
The dominant charge carrier in a n-type semiconductor is the
neutron.
hole
electron.
proton
Semiconductor elements are "doped" in order to
eliminate the possibility of incomplete bonds.
increase their electrical conductivity.
make them less susceptible to temperature changes.
make them electrically charged.
a.electrons, which are randomly organized about the nucleus.
b.no electrons beyond a closed shell.
c.four outer electrons beyond a closed shell.
d.outer electrons which cannot move.
Explanation / Answer
1. There are several elements that we regard as semiconductors. The common property of these elements is that they have
ANSWER: a, beacause electrons are distributed around the nucelus according to some principles
b is wrong because, on exitation electrons will go to exited state
c is wrong because only four electrons beyond the shell means exitation is limited which is not possible always
d is wrong because some electrons will go to exited state by taking engrgy
2. The dominant charge carrier in a n-type semiconductor is the
electrons
3. Semiconductor elements are "doped" in order to
increase their electrical conductivity.
