What is Surface Effects On Elastic Properties of Silver Nanowires: Contact Atomic-Force Micros about?

This study investigates the elastic properties of silver nanowires with diameters ranging from 20 to 140 nm using contact atomic force microscopy. It finds that the apparent Young modulus decreases with increasing diameter, stabilizing at larger sizes due to surface effects such as surface stress and oxidation. A theoretical analysis is presented to explain this size dependence, incorporating both surface stress and surface moduli, and emphasizes the importance of careful interpretation of experimental resu
