Donor Atom in Semiconductor

When a donor atom is added to a semiconductor, it can have an impact on the properties of the semiconductor. Donor atoms are atoms that have one more valence electron than the atoms that make up the semiconductor.

Impact of Donor Atom

The addition of a donor atom to a semiconductor can cause it to become an n-type semiconductor. This means that it has an excess of negative charge carriers, or electrons. This is because the extra electron on the donor atom is able to move freely throughout the semiconductor, making it more conductive.

Charge of Donor Atom

When a donor atom is added to a semiconductor, it loses an electron and becomes a positively charged ion. This is because the extra electron it had is donated to the semiconductor, leaving the donor atom with a net positive charge.

Donor Atom and Holes

In addition to donating an electron, a donor atom can also create a hole in the semiconductor. A hole is an absence of an electron in the valence band of the semiconductor. When a donor atom donates an electron to the semiconductor, it leaves behind a hole in its original position. These holes are able to move through the semiconductor, making it more conductive.

Conclusion

In summary, when a donor atom is added to a semiconductor, it loses an electron and becomes a positively charged ion. It also donates an electron to the semiconductor, creating an excess of negative charge carriers and a hole in the semiconductor. This overall leads to the semiconductor becoming more conductive and potentially becoming an n-type semiconductor.

When a donor atom is added to a semiconductor,
donar atom means one excessive electron is their and to acquire stable state this donar atom is in search of hole, if it found hole then due to recombination of electron hole pair it loose extra electron and create deficiency over it.
