From the perspective of bond relaxation and bond vibration, we have formulated the Raman
phonon relaxation of graphene, under the stimuli of the number-of-layers, the uni-axial …

One-to-one comparisons between indentation experiments and atomistic modelling have
until recently been hampered by the discrepancy in length scales of the two approaches …

With structural miniaturization down to the nanoscale, the detectable quantities of solid
materials no longer remain constant but become tunable. For the II–VI semiconductors …

A mechanically formed electrical nanocontact between gold and tungsten is a prototypical
junction between metals with dissimilar electronic structure. Through atomically …

From the perspective of bond order-length-strength correlation and the local bond averaging
approach, we have formulated the number-of-layer resolved Raman shifts of graphene, with …

Various types of nanometer-sized structures have been applied to advanced functional and
structural devices. Inherent structures, thermal stability, and properties of such …

Atomic-undercoordination-induced local bond contraction, bond strength gain, and the
associated temperature (T)-dependent atomic-cohesive-energy and binding-energy-density …

The tensile deformation and successive fracture process of tantalum (Ta) nanocontacts
(NCs) while applying various bias voltages was observed in situ by high-resolution …

Using silver and gold, we have measured the size‐dependence of the yield strength of
atomic‐sized samples as small as a single‐atom bridge, with pico‐level resolution in the …

We observed the tensile deformation of molybdenum (Mo) nanocontacts (NCs) and
simultaneously measured their conductance by in situ transmission electron microscopy …
