Miniaturization of structural components and functional devices have led to the development of new technologies such as micro-electro-mechanical systems, micro-engines, smart structures, lab-on-a-chip, three-dimensional integrated circuit, and bio-medical sensing devices, etc. However, the above-mentioned systems and devices have one issue in common. In order to perform their functionalities, they must maintain their structural integrity and reliability during their service life. Thus, the strength and time-dependent mechanical properties are major concerns for design engineers and device manufacturers. To characterize these mechanical properties, a powerful tool of nanoindenter has been developed during the past two decades. Our Excellence Research Project integrates the core competencies of College of Engineering and consists of five sub-projects to explore the fundamentals that dictate the mechanical properties of the cutting-edge materials processed in our college. This can only be achieved by synergetic integration of the capabilities of (i) processing of cutting-edge materials, (ii) nanoindenter probing the material in the nanometer scale, (iii) microscopies with atomic spatial resolution, and (iv) coupled atomistic and continuum analyses. Our team members are experienced and reputable researchers in related fields. Full support of this project would help the team to move to the new horizon and strengthen NTU`s position as a leader in the research and development of cutting-edge materials.微製造奈米科技機械性能米壓痕試驗機尖端材料micromanufacturingnanotechnologymechanical propertiesnanoindentercutting-edge materials
