摘要： Herein disclosed is a semiconductor device in which control means for carriers migrating in a first semiconductor (11) includes an interface state layer (12) lying on the first semiconductor (11) and a second conductor layer (13) lying on the interface state layer (12). The interface state layer (12) has its Fermi level pinned to that of the second semiconductor layer (13). By thus constructing an FET or the semiconductor device, an inversion or storage layer can be easily formed in the interface merely by applying a voltage to the control means.

摘要： Disclosed is a semiconductor device comprising a control electrode (30) for forming carriers at a junction interface between first and second layers (17.12) of different materials and for controlling the carriers, a first electrode (29) which is electronically connected to the carriers, and a second electrode region (18) for taking out the carriers in a direction perpendicular to the junction interface. Since the two-dimensional carriers are caused to flow as a current in the direction perpendicular to the plane at which the carriers exist, a large current can be derived as an operating current.

摘要： A semiconductor laser with an active layer (3) between two cladding layers (2,4) has grooves (30) formed in the substrate (1) below the lower cladding layer (2) and corresponding diffusion regions (6) with additional diffusion regions (6) between the grooves. This defines stripe regions in the laser device. Electrodes (7) are associated with the diffusion regions (6) forming part of the stripe regions, and electrodes (8) are associated with the other diffusion regions, in the gaps between the stripes. By applying a current to the electrodes 8 only, the fundamental supermode of the laser is excited, whilst by applying a current to the electrodes 7 only, a supermode of the highest order is excited. Since these two supermodes cause the emission of laser radiation at different angles, the angle of laser radiation from the device may be changed by changing the pattern of current to the electrodes (7,8).
Other embodiments achieve a change in the direction of the laser radiation by the use of electrodes with gaps, and by the use of electrodes outside the part of the device containing the stripe regions.

摘要： A high-power low-noise semiconductor laser device required for light sources for an erasable optical disc and a method of manufacturing the device are disclosed. Especially, a self-sustained pulsating semiconductor laser device is disclosed in which an MQW structure is used for an active layer (4, 44 or 44a), and thus a kink output power and a light output power by which the self-pulsation is enabled are increased to 10 mW or more and noise is reduced. Another semiconductor laser device of a self-pulsation type is disclosed in which impurities are doped in the active layer to reduce the self-pulsating frequency to obtain a low-noise characteristic even if higher optical feeback occurs.
