Can anybody tell me what actually is difference between between electron hole and positive ion.
A hole is an empty space where an electron is missing in an atom or molecule, while a positive ion is an atom or molecule that has lost one or more electrons, resulting in a positive charge.
Holes and positive ions can both contribute to the electrical conductivity of a material. Holes act as charge carriers, similar to electrons, while positive ions can also move and create a flow of electric current.
Holes are formed when an electron is excited and jumps to a higher energy level, leaving behind an empty space. Positive ions are formed when an atom or molecule loses one or more electrons, often due to interactions with other charged particles or high-energy radiation.
No, holes and positive ions are always present together in a material. As electrons move and create holes, positive ions are also formed to balance out the charge.
Holes and positive ions play a crucial role in the conductivity of semiconductors. In p-type semiconductors, holes are the dominant charge carriers, while in n-type semiconductors, positive ions play a role in creating an electric field that facilitates electron flow. This allows semiconductors to be used in electronic devices such as transistors and solar cells.
