Why is hole mobility less? Conduction electrons (free-electrons) travel in the conduction band and valence electrons (holes) travel in the valence band. Since holes are subjected to the stronger atomic force pulled by the nucleus than the electrons residing in the higher shells or farther shells, holes have a lower mobility. How is carrier mobility […]
Why does current change from positive to negative?
Why does current change from positive to negative? The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires […]

What type of stress is strike-slip fault?
What type of stress is strike-slip fault? A strike-slip fault is a nearly vertical dip-slip fault in which fault blocks move horizontally, parallel to the fault strike.
