  • Patent number: 9257540
    Abstract: A magnetic field effect transistor is presented. A magnetic field effect transistor comprises a current control part and a magnetic field applying part. A current control part comprises multiple electrodes and a current flowing material region located between multiple electrodes and in which the amount of current flowing between the electrodes is changed, and a magnetic field applying part applying a magnetic field generating from a magnetization state, which changes according to external input, of a pre-set material. By controlling current by using magnetic fields, high speed operation is possible as charging time is not required, and calculation results may be stored without external power supply because magnetic field is supplied by altering magnetization state of a material according to external input.

  • Patent number: 8237236
    Abstract: An InSb-based switching device, which operates at room temperature by using a magnetic field controlled avalanche process for applying to magneto-logic elements, is provided. A switching device of one embodiment includes a p-type semiconductor layer; an n-type semiconductor layer; and contact layers disposed on one of the p-type and n-type semiconductor layers, the p-type semiconductor layer being in contact with the n-type semiconductor layer such that a current can be applied through the contact layers to the p-type and n-type semiconductor layers to cause a current flow from one of the contact layers to the p-type and n-type semiconductor layers and from the p-type and n-type semiconductor layers to the other of the contact layers, whereby the current flow can be controlled by an intensity of a magnetic field applied to the p-type and n-type semiconductor layers substantially perpendicularly thereto.

  • Patent number: 7872321
    Abstract: A hybrid semiconductor-ferromagnet device is a device which has micromagnets (Co) deposited on semiconductor (InAs) two-dimensional electrons, and which has a junction structure of positive and negative magnetic field regions using a stray field resulting from the micromagnets. The magnetoresistance measured in the hybrid semiconductor-ferromagnet device has an asymmetrical hall resistance profile, and a change in magnetoresistance thereof is very large. The measured data is well consistent with the calculated results using a diffusive mode and a ballistic model.
