    摘要: The use of surfactants that do not themselves act as dopants and are isoelectronic with either the group III or group V host atoms during OMVPE growth significantly reduces the incorporation of background impurities such as carbon, oxygen, sulfur and/or silicon. For example, the use of the surfactants Sb or Bi significantly reduces the incorporation of background impurities such as carbon, oxygen, sulfur and/or silicon during the OMVPE growth of III/V semiconductor materials, for example GaAs, GaInP, and GaP layers. As a result, an effective method for controlling the incorporation of impurity atoms is adding a minute amount of surfactant during OMVPE growth.

    摘要: The invention relates to a tube coupling (TC2) for connecting an object (22) to one end of a tube (20) in a UHV tight manner, withstanding pressures up to several hundred bars and accommodating temperature differences from heating or cooling, said tube coupling (TC2) comprising said tube (20) and a tube fitting (10), wherein said tube fitting (10) comprises a basically cylindrical body (11) with a first central bore for receiving said tube (20), such that said tube (20) is axially supported by a radially extending shoulder (18) at the inner end of said first central bore, and wherein said tube (20) is pressed with its end face against said radially extending shoulder (18) by means of a gripping arrangement (13, 14, 15). The vacuum capability is achieved with simple components by providing a gasket (21) between said end face of said tube (20) and said radially extending shoulder (18) at the inner end of said first central bore (16).
