Electromigration Lifetime of Penta-Twinned Gold Nanowires: Implications for Flexible Electronics

“…These two effects broaden the probability distribution. This broadening of failure distributions with reducing size is seen in other failure domains, for example, in mechanical failure of nanostructures in general, and nanowires in particular . This fact may explain the larger overall variation of failure times in nanowires compared to that in interconnects: Although nanowires should have fewer defects due to being chemically synthesized instead of being polycrystalline deposited films, they are significantly shorter (several microns vs 1 μm, similar in width) and thus have much smaller volume.…”

A mathematical model development to investigate the impact of key parameters on the generated voltage hysteresis of silicon anode based lithium half cells

“…OCP values helped the model generated curve to follow a plot trend similar to experimental curves. Before developing our own mathematical model, we conducted literature surveys (Hossain and Kim, 2020b;Tanim et al, 2015;Sikha et al, 2014;Christensen and Newman, 2006;Safari and Delacourt, 2011;Jagannathan and Chandran, 2014;Chandrasekaran et al, 2010;Zhang et al, 2007;Hossain et al, 2020;Masud et al, 2021;Hossain et al, 2022a;Hossain et al, 2022b;Ojeda et al, 2022) figured out the parameters required to develop a battery model. Next, the best possible ranges were discovered for those parametric values.…”

Effects of radiation damage on the yielding and fracture of nanowires

“…42 Regarding the lack of size dependence for the strain at fracture, rather than interpreting the lack of visible correlation between the observed fractures strains and the nanowire diameters as a lack of correlation altogether, we instead estimate that the number of simulations performed was insufficient to capture the mean values of the expected distributions. Indeed, previous experimental 7 and computational 4 studies have shown that fracture properties (such as fracture strain or fracture position along the nanowire) do correlate with the diameter of nanowires to some extent with broad distributions that can obfuscate trends without sufficient data to properly capture the mean and the variance of these distributions. Size dependence on the fracture of nanowires has been observed experimentally 37,43 albeit for much bigger diameters in the sub-micron scale as well as much lower strain rates.…”

“…The fracture of nano-sized objects remains hard to predict using classical continuum fracture theory due to surface effects and the confinement of deformation mechanisms that are not present at higher length scales. The fracture of nanowires under tension has been explored both computationally and experimentally across a wide range of states, including wire shapes and diameters, [1][2][3][4][5][6][7][8] crystalline phases and orientations, 1,5,8,9 aspect ratios, 10,11 temperatures, 1,12 and strain rates. 4,10,13 For example, Wang et al 4 performed many molecular dynamics simulation trials for gold (Au) nanowires of various lengths and cross-sectional areas under tension, and noted a size dependence on the first yield stress and first yield strain, as well as a large variance in the position of fracture depending on both the cross-sectional area of the nanowires and the strain rate.…”

Ojeda et al 7 developed a highthroughput experimental methodology for examining the fracture of silver (Ag) nanowires under tension and observed sizedependent probability distributions for fracture strains. Sun et al 11 performed molecular dynamics simulations of twinned copper (Cu) nanowires and observed that the failure modes of the nanowires transitioned between brittle fracture to ductile fracture, depending on the length of the nanowires as well as the spacing between twin boundaries that had been inserted into the nanowires.…”
