  • Patent number: 10910053
    Abstract: A method of switching a cell of a memory that consists of cell components formed in a three-dimensional crystal with their own electrical connections and logical cell switching circuits, said method involving the exchange of data with the cells, wherein said exchange is carried out simultaneously with the aid of logical switching circuits and a focused stream of charged particles or electromagnetic radiation, which is directed at one or several of the faces of the crystal onto which a portion of mutually perpendicular electrical connection lines exit. The method simplifies cell switching and does not necessitate switching circuits on all of the faces of a three-dimensional crystal.

  • Patent number: 10403753
    Abstract: The invention relates to heterostructures including a layer of a two-dimensional material placed on a multiferroic layer. An ordered array of differing polarization domains and surface charges in the multiferroic layer produces corresponding domains having differing properties in the two-dimensional material. When the multiferroic layer is ferroelectric, the ferroelectric polarization domains in the layer produce local electric fields that penetrate the two-dimensional material. The local electric fields and surface charges can control the structural phase of the two-dimensional material, which in turn determines whether the two-dimensional material layer is insulating or metallic, has a band gap or no band gap, and whether it is magnetic or non-magnetic. Methods for producing the heterostructures are provided. Devices incorporating the heterostructures are also provided.

  • Patent number: 9285279
    Abstract: A tunable tunnel junction thermometry circuit includes a variable width tunnel junction between a test object and a probe. The junction width is varied and a change in thermovoltage across the junction with respect to the change in distance across the junction is determined. Also, a change in biased current with respect to a change in distance across the junction is determined. A temperature gradient across the junction is determined based on a mathematical relationship between the temperature gradient, the change in thermovoltage with respect to distance and the change in biased current with respect to distance. Thermovoltage may be measured by nullifying a thermoelectric tunneling current with an applied voltage supply level. A piezoelectric actuator may modulate the probe, and thus the junction width, to vary thermovoltage and biased current across the junction. Lock-in amplifiers measure the derivatives of the thermovoltage and biased current modulated by varying junction width.

  • Patent number: 8679611
    Abstract: A dielectric material layer is deposited on exposed surfaces of a bonded structure that includes a first substrate and a second substrate. The dielectric material layer is formed on an exposed planar surface of a second substrate and the entirety of peripheral sidewalls of the first and second substrates. The dielectric material layer can be formed by chemical vapor deposition, atomic layer deposition, or plasma induced deposition. Further, the dielectric material layer seals the entire periphery of the interface between the first and second substrates. If a planar portion of the dielectric material layer can be removed by planarization to facilitate thinning of the bonded structure, the remaining portion of the dielectric material layer can form a dielectric ring.

  • Patent number: 8649249
    Abstract: A novel method and apparatus is provided for printing magnetic patterns using heat assisted magnetic recording (HAMR). The apparatus includes an array of probes that is arranged in a predetermined pattern, such as a servo pattern. The array of probes is brought into contact, or near-contact, with a magnetic recording medium that has been bulk erased substantially along an initialization direction. Each probe is energized so as to heat its respective contacted (or near-contacted) region of the recording medium above a threshold temperature. An external magnetic field is applied to the heated regions in a direction that is substantially opposite from the initialization direction. The strength of the external magnetic field is chosen to be greater than the coercivity of the recording medium at the threshold temperature, but less than the coercivity of the recording medium at room temperature. As a result, only magnetizations in the heated regions become aligned with the external field.

  • Patent number: 8644125
    Abstract: A seek-scan probe (SSP) memory involves multiple-wafer bonding needing precision small gaps in between. Solder reflow bonding is typically used to join the wafers due to its reliability and ability to hermetically seal. However, solder reflow bonding may not provide a consistently controllable gap due to flowing solder during the bonding process. Thus, a bond stop technique and process is used to provide accurate cantilever to media gap control.

  • Patent number: 8553517
    Abstract: A magnetic medium using spin-polarized electrons, and an apparatus and method of recording data on the magnetic medium are provided. The magnetic medium includes a polarization layer and a magnetic recording layer. The polarization layer spin-polarizes electrons. In the magnetic recording layer, the direction of magnetization varies depending on the direction of the spin-polarization of the electrons. The data recording apparatus includes a light source and a probe. The light source radiates circularly polarized light, and the probe injects electrons spin-polarized by the circularly polarized light into a magnetic medium and changes the direction of the magnetization of the magnetic medium to record data on the magnetic medium. Because the direction of magnetization is adjusted using spin-polarized electrons, fast data recording can be achieved.

  • Patent number: 8427929
    Abstract: A property, such as a quality parameter, of a write pole in a write head is determined using an optical metrology device, where the write pole is smaller than the optical resolution limit of the metrology device. The metrology device produces polarized light that is reflected off the write pole while the write pole is magnetized either during or after excitation with a write current. The magnetization alters the polarization state of the light, which can be analyzed to transform the altered polarization state into intensity. The intensity of the light is detected over the point spread function of the optics in the metrology device and an intensity value is generated. The intensity value is used to determine the quality parameter of the write pole, e.g., by comparison to a threshold or reference intensity value, which may be generated empirically or theoretically.
