Brittle fracture to recoverable plasticity: polytypism-dependent nanomechanics in todorokite-like nanobelts

“…This data processing procedure has been explained in detail in our past reports and can be found elsewhere. 23,24 From this plot, it can be observed that the T-NB undergoes fracture. This is also further conrmed with an AFM scan obtained from the device aer the three-point test (panel 'e').…”

“…Further details on this technique can be found in our past reports, where this approach has been employed to assemble and characterize the physical properties of other one-dimensional nanomaterials. [21][22][23][24] As shown in Fig. 2(a and b), each device consists of a pair of 150 nm thick gold nanoelectrodes, which are separated by a design gap of either 600 nm or 1 mm in different designs.…”

“…2(c). 13,[23][24][25][26] This process involves the following steps: (a) positioning of the AFM tip in nanoscopic proximity to but, directly above the NB mid-length using a tapping mode-scan taken prior to the bending test, (b) movement of the sample stage z-piezo to bring the NB sample in contact with AFM tip, thereby inducing out-of-plane deections in both, the tip and the NB, and (c) the recording of the tip deection vs. stage movement (i.e., its z-piezo) plot during this process. If the spring constant of the AFM tip is pre-calibrated (using the Sader's method 13 ), the tip deection vs. z-piezo plot can be converted to the NB force (F NB ) vs. deection (d NB ) plot, as shown in Fig.…”

“…We dene the critical load (F y ), associated with the yield point, as the load at which the plastic deformation reaches 2 nm (in order to distinctly locate the yield point above the measurement noise). The yield strength of the NB can then be computed as: 23,24…”

Investigation of Structural, Electronic, Optic and Elastic Properties of Perovskite RbGeCl3 Crystal: A First Principles Study

“…Mostly it is seen in composite materials. When we look at our crystal, we see that the stiffness of Germanium is 91,9 GPa [27] which is immensely bigger than Rubidium (2,4 GPa) [28] and Chloride (no…”
