Erratum: “Probing lattice dynamics in ST 12 phase germanium nanowires by Raman spectroscopy” [Appl. Phys. Lett. 119, 232105 (2021)]

In the original published article,¹ the authors forgot to include Ahin Roy and Valeria Nicolosi of School of Chemistry and CRANN & AMBER Centre, Trinity College Dublin, Dublin 2, Ireland, who have contributed to record the HAADF-STEM image from the sample. In this erratum, we include them in the author byline and make some minor corrections in one image and text (mostly, the word HRTEM is replaced by HAADF-STEM). The corrections are given below:

The modified author byline as follows:

In the original published article,¹ Fig. 1(d) should be replaced by the figure shown below, as the FFT presented in the inset of Fig. 1(d) of the published article was not from the same image, and the spots in the FFT were wrongly marked as a family of directions, whereas they should actually be indexed as specific planes.

In the original published article,¹ the caption of Fig. 1(d) should be replaced by “Lattice-resolved HAADF-STEM image and corresponding FFT (in the inset) of ST12-Ge nanowires.”

In the original published article,¹ in the second paragraph of the left column of p. 3, the sentence “HRTEM and Fast Fourier Transform (FFT) were used to further confirm the formation of ST12-Ge crystalline phase in the NWs and also verify the structural quality of the ST12-Ge NWs [Fig. 1(d)]” should be replaced by “HAADF-STEM imaging and Fast Fourier Transform (FFT) were used to further confirm the formation of the ST12-Ge crystalline phase in the NWs and also verify the structural quality of the ST12-Ge NWs [Fig. 1(d)].”

In the original published article,¹ in the second paragraph of the left column of p. 3, the sentence “HRTEM image recorded with ⟨110⟩ zone axis alignment reveals an interplanar spacing (d) of 0.21 nm corresponding to the (220) plane of the ST12-Ge crystal structure (JCPDS No. 72-1089)” should be replaced by “HAADF-STEM image recorded with ⟨110⟩ zone axis alignment reveals an interplanar spacing (d) of 0.21 nm corresponding to the (220) plane of the ST12-Ge crystal structure (JCPDS No. 72-1089).”

In the original published article,¹ in the second paragraph of the left column of p. 3, the sentence “A hexagonal symmetry was observed in the FFT pattern where the spots are associated with the (111) and (220) planes [inset of Fig. 1(d)] where ⟨110⟩ is the growth direction of the ST12-Ge NW” should be replaced by “The spots observed in the FFT pattern are associated with the (111) and (220) planes [inset of Fig. 1(d)] where ⟨110⟩ is the growth direction of the ST12-Ge NW.”
