    摘要: A method for repeatably fabricating GaAs/ZnSe and other III-V/II-VI semiconductor interfaces with relatively low stacking fault densities in II-VI semiconductor devices such as laser diodes. The method includes providing a molecular beam epitaxy (MBE) system including at least a group III element source, a group II element source, a group V element source and a group VI element source. A semiconductor substrate having a III-V semiconductor surface on which the interface is to be fabricated is positioned within the MBE system. The substrate is then heated to a temperature suitable for III-V semiconductor growth, and a crystalline III-V semiconductor buffer layer grown on the III-V surface of the substrate. The temperature of the semiconductor substrate is then adjusted to a temperature suitable for II-VI semiconductor growth, and a crystalline II-VI semiconductor buffer layer grown on the III-V buffer layer by alternating beam epitaxy. The group II and group VI sources are operated to expose the III-V buffer layer to a group II element flux before exposing the III-V buffer layer to a group VI element flux.

    摘要: We have observed anomalous behavior of II-VI semiconductor devices grown on certain semiconductor substrates, and have determined that the anomalous behavior is likely the result of indium atoms from the substrate migrating into the II-V layers during growth. The indium can thus become an unintended dopant in one or more of the II-VI layers grown on the substrate, particularly layers that are close to the growth substrate, and can detrimentally impact device performance. We describe a variety of semiconductor constructions and techniques effective to deplete the migrating indium within a short distance in the growth layers, or to substantially prevent indium from migrating out of the substrate, or to otherwise substantially isolate functional II-VI layers from the migrating indium, so as to maintain good device performance.
