Latest Patents

Sugiura holds a patent for a solid-state radiation detector that utilizes a single crystal of compound semiconductor InSb. This invention employs a high-purity InSb single crystal that is not artificially doped with impurities, serving as an effective radiation detecting medium. To achieve diode characteristics, a gold-palladium alloy is used to form a surface barrier layer. At a temperature of 4.2 K, the device resistance of the fabricated solid-state radiation detector reaches as high as 1.4 kΩ, while the rise time of output signals from a charge-sensitive preamplifier is as short as 0.4 µs. This indicates a reduction in the trapping of electrons or positive holes. Furthermore, the detector is capable of measuring α-ray spectra over a temperature range from 2 K to 50 K.
