What are the elements of a semiconductor?
The elemental semiconductors are those composed of single species of atoms, such as silicon (Si), germanium (Ge), and tin (Sn) in column IV and selenium (Se) and tellurium (Te) in column VI of the periodic table. There are, however, numerous compound semiconductors, which are composed of two or more elements.
What is semiconductor with diagram?
Difference Between Intrinsic and Extrinsic Semiconductors
Intrinsic Semiconductor | Extrinsic Semiconductor |
---|---|
Pure semiconductor | Impure semiconductor |
Density of electrons is equal to the density of holes | Density of electrons is not equal to the density of holes |
Electrical conductivity is low | Electrical conductivity is high |
What is an example of a semiconductor element?
Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called “metalloid staircase” on the periodic table. After silicon, gallium arsenide is the second-most common semiconductor and is used in laser diodes, solar cells, microwave-frequency integrated circuits, and others.
What is semiconductor describe two types of semiconductor?
Semiconductor is the solid which is perfect insulator at 0 K but conduct some electricity at room temperature. e.g., Silicon and Germanium. Two main types of semiconductors are n-type and p-type semiconductors. Silicon and germanium (Group 14) have very low electrical conductivity in the pure state.
What are the types of semiconductors?
Types of Semiconductors: Semiconductors are divided into two categories: Intrinsic Semiconductor. Extrinsic Semiconductor.
What groups on the periodic table are semiconductors?
The atoms in a semiconductor are materials from either group IV of the periodic table, or from a combination of group III and group V (called III-V semiconductors), or of combinations from group II and group VI (called II-VI semiconductors).
