个人简介
Andrew Briggs developed the application of acoustic microscopy to image and measure the elastic structure of a wide range of materials, developing the theory to explain how cracks and other defects give rise to surface wave contrast. His 1992 monograph Acoustic Microscopy remains in print, with a new chapter on acoustically excited probe microscopy in the second edition (2010). With J.-P. Salvetat he used atomic force microscopy to determine the elastic constants of single-walled carbon nanotube ropes, subsequently extending the work to multiwalled nanotubes and biological microtubules.
He used high temperature scanning tunneling microscopy to obtain new insights into the surfaces of oxides that are insulating at room temperature and into the growth of semiconductors in real time. His atomic resolution images of surfaces of UO2, NiO and CoO, and also TiO2 and CeO2 yielded information about the local electronic properties and bonding, paving the way for new theory. He used elevated temperature STM to understand homo- and heteroepitaxial growth on silicon surfaces. By using gas precursors he was able to visualize growth directly in real space with atomic resolution in real time, from single atom dynamics to growth of several monolayers.
