Abstract:
1. A magnetic transistor, comprising: a magnetic section; a thin semiconductor layer, disposed on the magnetic section; a first metal terminal, disposed on one end of an opposite surface to the thin semiconductor layer of the magnetic section and being in direct contact with the magnetic section to provide a conductive channel in the thin semiconductor layer; a second metal terminal, disposed on one end of an opposite surface to the magnetic section of the thin semiconductor layer and being in direct contact with the thin semiconductor layer to create a first conductive region in the thin semiconductor layer; a third metal terminal, disposed on the other end of the opposite surface to the magnetic section of the thin semiconductor layer and being in direct contact with the thin semiconductor layer to create a second conductive region in the thin semiconductor layer; and a control metal having no direct connection with the magnetic section, the thin semiconductor layer, and the first, second and third metal terminals, capable of providing an external applied field to control dipole direction in the magnetic section when having a current flowing therein; while the magnetic transistor is turned on, a current path is formed between the second metal terminal and the third metal terminal via the thin semiconductor layer.
