“…From rocking curve data, we already knew that untwinned material existed after the flip to the twinned orientation, but these measurements provided no information on the scale or nature of the defects. The X-ray diffraction imaging results are consistent with the observation by high resolution electron microscopy that the predominant defect in Cd 1-x Zn x Te thin films are lamellar twins and that they occur at high density [30].…”

“…Alikhanian et al have reported the first experimental investigation of the solid-vapor equilibrium in the CdTe-ZnTe system at 525 • C and 505 • C over the whole composition range [13]. The micro structural defects of MBE deposited Cd 1−x Zn x Te thin films with x ≈ 0.04 using HRTEM have been reported by different authors [14].…”

“…However, several studies describe the data from electron diffraction patterns that were initially assigned to 2H-Si as a double diffraction of superposed twinned crystals. − Moreover, the Raman peak shifts toward the expected value for the 2H-Si can be caused by defects and therefore are not necessarily a clear evidence for the presence of the metastable Si allotrope . Nevertheless, several reports describe the presence of 2H-Si using characterization methods capable of an unequivocal identification. , For instance, it is highly recommended/vital to use the [110] 3C /[12̅10] 2H zone axis to distinguish between double diffraction caused by twins and 2H-Si when using HRTEM/electron diffraction for the characterization .…”

Metastable Group IV Allotropes and Solid Solutions: Nanoparticles and Nanowires

In the past decades, group IV nanowires and nanoparticles have been the subject of extensive research. Beside tremendous progress in morphological control and integration in advanced device architectures, research on allotropes and metastable compositions has gained considerable interest. Several new approaches now allow the controlled formation of specific allotropes in the nanostructured form as well as chemical compositions not attainable by traditional synthesis protocols. The conditions applied to form these metastable solid solutions and allotropes are usually far from thermodynamic equilibrium or rely on unconventional templates. The increased interest in the field of metastable group IV nanostructures arises from their altered physical properties, including tunable, direct bandgaps with energies equivalent to the near- to mid-infrared spectral region as described for materials such as Ge1–x Sn x and hexagonal Si1–x Ge x . The implementation of these material characteristics in complementary metal oxide semiconductor (CMOS) processes are desirable for applications in electronics, optoelectronics, sensors, optics, etc. but also their use as nonsurface bound nanoparticles in sensing, nanobiotechnology and nanomedicine can offer additional opportunities. This review article highlights both the important advancements and still open questions for the continued development of these nanoscaled materials for next-generation device concepts.
