Answer

Indium is trivalent impurity so p type semiconduct

or will be obtained.

Answer

Germanium have 4 valence electron and indium have 3 valence electrons when we dope indium in germanium there is one positive hole obtain and we get p-type of germanium semiconductor...

Answer

Indium

Answer

Doping in Semiconductors

Doping is a process of adding impurities to a semiconductor to change its electrical properties. Intrinsic semiconductors like germanium and silicon have a balanced number of electrons and holes, and hence, they have a low level of conductivity. However, by doping them with impurities, their conductivity can be increased, and they can be used for electronic applications.

P-Type Semiconductors

P-type semiconductors are made by doping a pure semiconductor with impurities that have fewer valence electrons than the semiconductor. The impurities create holes in the valence band, which allows them to accept electrons from neighboring atoms and generate a net positive charge.

Doping of Germanium with Indium

Indium is a p-type dopant for germanium. When germanium is doped with indium, each indium atom replaces a germanium atom in the crystal lattice. Indium has three valence electrons, which is one less than the four valence electrons of germanium. Therefore, when indium is added to germanium, it creates a hole in the valence band, and this hole can accept electrons from neighboring atoms.

The indium atom acts as an acceptor and generates a net positive charge, making germanium a p-type semiconductor. The concentration of indium dopant atoms determines the level of conductivity of the germanium semiconductor.

Conclusion

In conclusion, to obtain a p-type germanium semiconductor, it must be doped with indium. The process of doping with indium generates holes in the valence band, which can accept electrons from neighboring atoms and create a net positive charge. The concentration of indium dopant atoms determines the level of conductivity of the semiconductor.
