Abstract: The present invention provides a reproducible preliminary in-situ oxide removal step for patterned self-assisted III-V semiconductor nanowire growth. Here “in-situ” means located within the same treatment environment or apparatus as the nanowire growth process, e.g. with a molecular beam epitaxy (MBE) apparatus or the like. Providing an in-situ process may prevent the formation of a thin oxide layer during transfer of the substrate into the nanowire growth apparatus.

Abstract translation: 一种半导体器件,包括硅衬底,在其上生长厚度<100nm厚的AlAs或相关化合物的外延层,之后是除GaN缓冲层之外的化合物半导体。 另外的III-V族化合物半导体结构可以在顶部外延生长。 AlAs外延层减少了与硅的界面的缺陷的形成和传播,因此可以改善在顶部生长的活性结构的性能。
