A nanotwinned structure deposited on a surface of a substrate is provided. The nanotwinned structure includes at least one domain, and the domain includes a plurality of nanotwins. Each of the nanotwins possesses a faced-centered cubic (FCC) structure. The plurality of nanotwins are stacked along the [111] crystallographic axis. Less than 50% of a surface of the nanotwinned structure takes the (111) as the preferred orientation.
