Answer;

D) It uses boron so that electrical conduction is due to the movement of electrons

Explanation;A semiconductor is a substance whose resistivity is between that of a good conductor and a good insulator.There are two types of semiconductor: n-type and p-type.A p-type semiconductor is one in which the impurity added produces extra holes available for conduction, e.g. boron (B) in silicon. Silicon having 4 electrons in it's outer shell while boron has 3 electrons. So a electron is 'missing', or we can say this acts like a positive hole.

Answer from: gavincoscarat760

D) It uses boron so that electrical conduction is due to the movement of a positive charge.

Explanation:

In p type semiconductor we have to add impurity which will enhance the number of holes in the pure semiconductor.

Here we know that semiconductors are device in which conductivity is very small as compare to conductors.

Now when we add some impurity of trivalent valency in it then the number of holed in such conductors will increase due to which conductivity will increase in semiconductors

SO here since Boron is the element in which its outermost shell has 3 electrons and when it is added to the semiconductor then it will add one hole per boron atom

this will increase the conductivity due to increase in the number of holes

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
