There is an unmet need for faster and more accurate measurements of nanoscale materials and devices. With compelling new applications in fields such as energy, electronics and healthcare there is an increasing drive to develop novel materials and scale-up from proof-of-concept demonstrations to practical implementations. Similarly, in industry, it is becoming apparent that understanding the nanoscale origins of metal fatigue and corrosion holds the key to more accurate lifetime estimations and the development of next generation coatings and components.
The high-speed atomic force microscope I have developed at the University of Bristol is an ideal diagnostic tool for the rapid characterisation of nanoscale surfaces. It is 1,000 times faster than a conventional atomic force microscope and enables the direct observation of molecular interactions and nanoscale processes with millisecond temporal resolution. In this talk I will discuss the development of the tool, including the underlying physics that empower it, key application areas enabled by these MHz measurements and future opportunities afforded by the technology.
