    摘要: In a semiconductor device including a stack structure having heterojunction units formed by alternately stacking GaN (gallium nitride) films and barrier films which are different in forbidden band width, a first electrode formed in a Schottky barrier contact with one sidewall of the stack structure, and a second electrode formed in contact with the other sidewall, an oxide film is interposed between the first electrode and the barrier films. Therefore, the reverse leakage current is prevented from flowing through defects remaining in the barrier films due to processing of the barrier films, so that a reverse leakage current of a Schottky barrier diode is reduced.

    摘要: The relationship between the reflectivity characteristic of a DBR layer(s), in which an InP layer and an InGaAlAs layer are laminated alternatively, and the optical absorption characteristic of the InGaAlAs layer, is a trade-off in a vertical cavity surface emitting laser on an InP substrate. The present invention applies a semiconductor DBR layer(s), in which an InP layer and an InGaAlAs-MQW (multi-quantum-wells) layer are laminated alternatively, in order to dissolve the above trade-off. The InGaAlAs-MQW layer is composed of InGaAlAs-wells and barriers. The InP layer is doped uniformly and the InGaAlAs-MQW layer has a structure in which at least a part thereof is doped.

    摘要: The object of the invention is to reduce the deterioration of crystallinity in the vicinity of an active layer when C, which is a p-type dopant, is doped and to suppress the diffusion of Zn, which is a p-type dopant, into an undoped active layer, thus to realize a sharp doping profile. When a Zn-doped InGaAlAs layer having favorable crystallinity is provided between a C-doped InGaAlAs upper-side guiding layer and an undoped active layer, the influence of the C-doped InGaAlAs layer whose crystallinity is lowered can be reduced in the vicinity of the active layer. Further, the Zn diffusion from a Zn-doped InP cladding layer can be suppressed by the C-doped InGaAlAs layer.

    摘要: Since the semiconductor devices including a stacked structure of group-III-V alloy semiconductor layers different in the kind of group-V constituent atom form the so-called band line-up of type II, band discontinuity in the heterostructure has impeded smooth transport of carriers and deteriorated device characteristics.According to the present invention, an energy band structure that makes it possible, in one energy band (e.g., a valence band), to smoothly transport carriers of one of two kinds (e.g., holes) by connecting energy discontinuity in an inclined form or stepwise, and at the same, in the other energy band (e.g., a conduction band), to maintain a barrier effect for carriers of the other kind (e.g., electrons) by retaining energy discontinuity, can be realized for improved transport characteristics of carriers at the heterointerface forming the band line-up of type II.
