In-situ nanowire measurement finds better deformability, strength
Researchers at NC State U. say they have measured properties of silicon nanowires using in-situ tensile testing, finding the material has far better elasticity and fracture properties than "regular" sized silicon material , suggesting potential for future electronics devices.
