Which will bring electricity is not good, but through the dop substances (Doping) by placing a chemical Atomic mix (Impurity) is a semiconductor is not pure (Extrinsic Semiconductor) which will make electrical as well.
It conducts electricity poorly. But over the doping substances (Doping) by inserting the impurity atom (Impurity) went into a semiconductor impurity (Extrinsic Semiconductor), which makes the electricity well.
The conductivity is poor, but when through the process โด๊ trimmed (Doping) by atom dopants (Impurity) in and make a semiconductor, not pure. (Extrinsic Semiconductor) which makes the conductivity as well.
