    摘要: A field-effect transistor or a bipolar transistor may be provided in which the contact resistance between a channel layer or base layer and a contact layer are reduced. For example, an InGaAs buffer layer may be formed on the substrate side of an InGaAs channel layer of a field-effect transistor and by the bypassing effect that carriers pass through this InGaAs buffer layer, the InGaAs channel layer comes in contact with the contact layer with a low resistance. The contact resistance between the InGaAs channel layer and the contact layer can be reduced to 10 ohm per a width of 10.mu.m, and as a result, the value of transconductance factor K of a field-effect transistor can be increased in 14 mA/V.sup.2 per a width of 10.mu.m.

    摘要: An optical modulator which utilizes the Stark effect according to which the absorption spectra change if an electric field is applied to the excitons. A thin film of a suitable thickness composed of a semiconductor and an insulator or composed of either one of them, is formed between a group of electrons and a group of positive holes that constitute excitons, so that the excitons are stabilized. The optical modulator performs the modulation at high speeds maintaining a high efficiency.

    摘要: A solid film forming apparatus, e.g., an MO-MBE (Metal-Organic Molecular Beam Epitaxy) apparatus, wherein evacuatable containers isolated from a growth chamber by a switching device and connected to raw material gas introduction pipings are provided between the growth chamber for a solid film, e.g., a compound semiconductor, and raw material gas introduction pipings. Growth of the solid film is controlled by opening and closing the switching device and evacuating the container at least while the switching device is closed during the growth of the solid film. An undesired influence on the growing film due to residual gas in the containers which are not used for growth can be prevented and, hence, interception and introduction of the raw material gas into the growth chamber can be performed with remarkably high controllability, and films of superior abruptness of the interface between films, e.g., the heterojunction of the compound semiconductor, can be obtained.
