Do holes (i.e. electron holes) have spin angular momentum like electrons do? Thanks for any insight you can give and if you can recommend any literature on the mater that would be great!
Thanks!
Thanks!

Navy said:Yes, hole (missing electron) does have a spin. Consider a filled Fermi sea with all the electrons paired up so as to make zero total spin angular momentum. If one electron is elected out (say by photo emission) it creates a hole behind. As the electron has spin plus half the remaining hole must has minus half spin to conserve the total spin angular momentum.
Electron holes are the absence of an electron in an atom's valence shell. They can be thought of as positively charged particles that behave similarly to electrons in some ways.
No, electron holes do not have mass. They are a conceptual construct used to describe the behavior of electrons in a material.
Yes, electron holes can move through a material as electrons shift in and out of the valence shell. This movement allows for the flow of electric current.
Yes, electron holes do have spin angular momentum, just like electrons. This is because they are a result of the spin of the electrons in a material.
Electron holes can affect the electrical, thermal, and optical properties of a material. They can also play a role in the behavior of semiconductor devices.
