Semiconductors can either be intrinsic or extrinsic. Intrinsic semiconductors are elements that are in their pure form. These will usually have positive and negative sides because the electrons migrate towards one direction. On the other hand, extrinsic semiconductors are when the conductivity (or ability to make an electric charge with the electrons) are controlled by adding other atoms. These atoms that are added are called dopants. Dopants donate or receive electrons from the semiconductor to make impure.
There are two types of extrinsic semiconductors. They are a) n-type semiconductors
b) p-type semiconductors.
n-type semiconductors: These are impure by fifth group elements like phosphorous, arsenic, antimony. In this type of semiconductors majority charge carriers are electrons and minority charge carriers are holes. These are donors of electrons.
p-type semiconductors: These are impure by third group elements like boron,indium. In this
type of semiconductors majority charge carriers are holes and minority charge carriers are electrons. These are acceptors of electrons.
Semiconductors were originally made using specially doped germanium or silicon. Nowadays various specialized doped alloys are used.
A diode is the simplest possible semiconductor device, and most semiconductor chips and transistors are created with silicon.
The two main types of semiconductors are n-type and p-type.
You shouldn't write "the following" if you don't provide the list. Anyway, silicon and germanium are most commonly used as semiconductors.
The ones adjacent to silicon.
Semimetals
It is called the Periodic Table of Elements.
CO3 is not placed in periodic table. Only elements are arranged in periodic table.
The periodic table.
In the modern day periodic table, the periodic table gets wider in periods two, four, and six.
N stands for Nitrogen on the periodic table.

metalloids
Metalloids or semiconductors
b
Boron, B belongs to the semiconductors(metalloids) family. Semiconductors are located toward the right side of the periodic table.
Metalloids. They are squeezed between metals and non-metals in the periodic table. They include silicon and germanium.
Non-metals, metals and semiconductors. Metals are on the left, non-metals on the right, and semiconductors sitting near the staircase line that divides the metals and non-metals.
The 14th element in the periodic table is silicon (Si). It is a non-metal with atomic number 14 and is known for its abundance in Earth's crust and its role in electronics and semiconductors.
A Periodic table The Periodic Table of the Elements.
total no of elements in periodic table is 112.Some of which are still unnamed. Elements on the periodic table is classifies into metals, non-metals, semiconductors, and elements that are radioactive. Elements are arranged in increasing order of their atomic number. In a periodic table on the left are the metals, on the right are all non-metals and in the middle are the transition metals.
