Abstract:

Some ternary semiconductor alloys spontaneously order during growth. We observe this phenomenon in some alloys grown for infrared IR applications by molecular beam epitaxy MBE. Ordering can affect not only the crystal structure, but also important optical and electronic properties that ultimately affect a materials suitability for IR device applications. It is important to be aware of the presence of ordering, which is not usually detectable by the standard 004 x-ray diffraction XRD measurements typically used as a simple measurement of film quality.
