“…Broad peaks in XRD analysis indicate distortions in the lattice parameter due to differences in the size of atoms resulting in decreased crystallinity. A broad peak could indicate an amorphous structure [ 30 ], the presence of small crystalline grains [ 31 ], or a nanolayer [ 32 ]. We therefore examined the structural changes in detail using TEM analysis.…”

Zr-Cu based thin-film metallic glass (TFMG) has good glass-forming ability and the addition of a third element can create a chaotic system capable of inhibiting the nucleation and growth of crystals. This study focused on TFMGs made with Zr, Cu, and Ti in various compositions deposited via high-impulse magnetron sputtering on silicon and 304 stainless-steel substrates. Detailed analysis was performed on the microstructure and surface characteristics of the resulting coatings. Transmission electron microscopy revealed that the multilayer structure changed to a nanocrystalline structure similar to an amorphous coating. The excellent hydrophobicity of Zr-Cu-Ti TFMGs can be attributed to their ultra-smooth surface without any grain boundaries. The excellent antimicrobial effects can be attributed to a hydrophobic surface resisting cell adhesion and the presence of copper ions, which are lethal to microbes.

“…Recently, our group reported that the ternary CuZrTi amorphous metal has excellent elastic deformation limit and structural stability compared to the binary CuZr amorphous metal. − A laminate structure in which two materials are repeatedly stacked may highlight the advantages of each material. So, the two types of layers can interact complementarily in terms of mechanical and electrical properties. − …”

Nanolaminate with alternating layers of nanocrystalline Cu and amorphous CuZrTi is suggested as highly stretchable and conductive interconnect material in stretchable devices. 50 nm nanocrystalline Cu and 20 nm amorphous CuZrTi are the optimum thicknesses of the constituent layers, which result in an elastic deformation limit of 3.33% similar to that of the monolithic amorphous CuZrTi film and an electrical conductivity of 11.83 S/μm corresponding to 70% of that of the monolithic nanocrystalline Cu film. The enhanced elastic deformability and conductivity of the nanolaminates enable the maintenance of the interconnect performance for cyclic stretching with a tensile strain of 114% in the form of a free-standing serpentine structure and a tensile strain of 30% in the form of an ordinary circular coil on an elastomer substrate.
