Latest Patents

One of Ishibashi's latest patents is a method and apparatus for detecting terahertz waves. This apparatus features a semiconductor chip with a two-dimensional electron gas formed at a constant position from its surface. It incorporates a carbon nanotube, a conductive source electrode, a drain electrode, and a gate electrode, all positioned in close contact with the chip's surface. The carbon nanotube extends along the chip, connecting with the source and drain electrodes, while the gate electrode is spaced at a uniform distance from the nanotube's side surface. The apparatus is equipped with an SD current detecting circuit to measure the current, a gate voltage applying circuit for adjustable gate voltage, and a magnetic field generating device to apply a variable magnetic field to the chip.

Another notable patent by Ishibashi is for a near-field terahertz wave detector. This innovative device includes a semiconductor chip whose longitudinal electrical resistance changes due to near-field terahertz waves. It is covered by an insulating film and features a conductive film that shields the terahertz wave, including an aperture that is significantly smaller than the wavelength of the terahertz wave. A planar conductive probe is positioned between the conductive film and the semiconductor chip, insulated by the insulating film. This design greatly enhances the signal-to-noise ratio, allowing for high-efficiency near-field wave detection and increasing the object's resolution to one-tenth or less of the wavelength.
