positive hole मीनिंग इन हिंदी

These sites are filled by Te atoms which are ionized to create additional positive holes.
Due to the generation of positive holes and electrons, oxidation-reduction reactions take place at the surface of semiconductors.
In the oxidative reaction, the positive holes react with the moisture present on the surface and produce a hydroxyl radical.
It is used as well to find the sign of the dominant charge carriers in materials such as semiconductors ( negative electrons or positive holes ).
When a photon with energy equal to or greater than the materials band gap is absorbed by the semiconductor, an electron is excited from the valence band to the conduction band, generating a positive hole in the valence band.
