Further analysis of the multiphase area in the cross-section uncovers segments of other suboxides (e.g., W5O14) and variations in pentagonal column stacking and various defects which are not discussed any further in the current work. Notably, the cross-sectional analysis may provide insight into the growth discrepancies observed during the in-situ nanowhisker growth within the TEM (Fig. ). The growing structures, misaligned with previous layers, might have contained different phases which were observed in Fig. .
