    Abstract: A pump beam irradiates the surface of a semiconductor sample through modulator while irradiating the surface with a probe beam so that a detector measures a light-modulated spectrum of the probe beam reflected from the surface of the semiconductor sample. Then, surface electric field strength is calculated from the period of Franz-Keldysh oscillations appearing in the light-modulated spectrum, and the surface recombination velocity and surface Fermi level are calculated based on a relation between the surface electric field strength and the probe beam power density.

    Abstract: A commodity inspection system attaches a ferromagnetic body to a genuine commodity in advance and detects the magnetic characteristic of the ferromagnetic body so as to judge whether the inspection object is a genuine commodity. The system includes: an magnetization coil for applying a magnetic field changing at a predetermined frequency to a inspection object; a detection coil for detecting the change of the magnetic flux density caused by the magnetic field change; an FFT unit for acquiring a frequency spectrum corresponding to magnetic flux density change; and a judgment unit for judging whether the inspection object is a genuine commodity according to the acquired frequency spectrum. The ferromagnetic body causes a steep magnetization reversal when a magnetic field exceeding its coercive force is applied. Unlike an ordinary ferromagnetic body, in this ferromagnetic body, the frequency spectrum corresponding to the change of magnetic flux density caused by the magnetic field changing at a low frequency has a high-frequency component of large amplitude. Accordingly, it is possible to easily judge whether the inspection commodity is genuine commodity.

    Abstract: In a method of evaluating a piezoelectric field, non-destructive spectrometry of piezoelectric fields is performed in a semiconductor heterojunction using a technique different from PR spectroscopy. In the method, at first, first and second absorption spectra are measured by irradiating the sample with infrared light at first and second angles, respectively. Then, a peak position of an absorption band having incident-angle dependent intensity is specified, based on the first and second absorption spectra. Thus, the piezoelectric field strength is obtained using a relationship between the piezoelectric field and an electron energy level corresponding to the peak position.
