InOOH Bulk Crystals and Ultrathin Nanowires under Compression.
Ontology highlight
ABSTRACT: InOOH bulk crystals and ultrathin nanowires have been investigated under high pressures by in situ synchrotron radiation X-ray diffraction measurements at ambient temperature. The anisotropic compression indicates that the b-axis is more compressible than the other two axes in InOOH under hydrostatic conditions. Two inflection points, which are associated with the hydrogen-bond strengthening, can be reflected in the plots of b/c ratio versus pressure (b/c–P plots). The size-induced enhancement of the bulk modulus can be visualized from the P–V plots. By comparing the differences in the compression of bulk InOOH and ultrathin nanowires, it is validated that the nanosize effects play an important role in the high-pressure behaviors of InOOH.
