Thin film metallic glasses (TFMGs) are emerging materials characterized by a unique combination of mechanical/electrical properties involving large yield strength close to the theoretical limit, large ductility (> 10%) and metallic-like electrical conductivity. Nevertheless, the synthesis of advanced TFMGs with engineered microstructure and the understanding of their mechanical/electrical properties is barely tackled, limiting potential applications for stretchable electronics. Here, we report the use of Pulsed Laser Deposition (PLD) as a novel technique to synthetize nanostructured Zr50Cu50 (%at.) TFMGs. We show how the control of PLD process parameters (background gas pressure and laser fluence) enables to synthetize a variety of film microstructures among which compact fully amorphous and amorphous nano-granular resulting from cluster-assembled growth showing lower density and large free volume interfaces. Compact TFMGs show large elastic modulus (140 GPa) and hardness (10 GPa) which decreases for nanogranular films, while in-situ TEM tensile tests reveal an outstanding and tunable yield strength (3 GPa) and ductility (> 9%) product. Finally, we developed a stretchable transparent electrode based on nanogranular TFMGs nanotrough network showing excellent stretchability (70%) and low sheet resistance (~3 Ω/sq) which is then integrated in wirelessly rechargeable transparent heater, demonstrating the potential of these films for novel stretchable electronic devices.
