Crystalline, Phononic, and Electronic Properties of Heterostructured Polytypic Ge Nanowires by Raman Spectroscopy
Nano Letters, 18, 11, 7075-7084 (2018)
Artist view of a heterostructured Ge nanowire where cubic (in red) and hexagonal (in dark yellow) domains are alternated. Sketches of the Raman spectra acquired are also shown. Two segments of the nanowire are textured with the corresponding TEM image.
