Developing a simple method for characterising the mechanical properties of nanowhiskers (2013–2015)
Nanowhiskers are key building blocks of future generation nanodevices. However, the current methods for measuring mechanical properties of nanowhiskers are inaccurate and can produce contradictory results, due to the lack of comprehensive understanding of their deformation physics and the extreme challenge in mastering sophisticated measuring methodologies. This project aims to develop a simple method that combines loop bending with resonant vibration testing, to accurately measure elastic modulus and yield, tensile and fracture strengths of nanowhiskers. Successful outcomes from this project will not only solve a long-standing problem in the application of nanowhiskers, but provide new understanding of deformation science at the nanoscale.
