The dielectric constant is defined as the insulating material that can store charge when it is placed between two metallic plates.
It is the ratio of the electric permeability of the material to the electric permeability of free space.
\(\epsilon_r={\epsilon\over \epsilon_o}\)
The semiconductor elements (silicon and germanium) in their purest form have the highest dielectric constant.
Oxides of semiconductors have less dielectric constant as compared to nitride of semiconductors.
Material |
Dielectric constant |
Silicon oxide (SiO2) |
3.9 |
Silicon nitride (Si2N4) |
7.5 |
Gallium Arsenide (GaAs) |
12.88 |
Germanium (Ge) |
16 |
Hence, the correct answer is option D.
