Looking up from the diamond-cubic structures of Si and Ge


A/Prof. Jodie Bradby, The Australian National University
This colloquium will be held 3 pm, 15th October, in Parnell 07-222.


Currently there are over 12 different pressure-induced phases of silicon, several of which are stable at ambient conditions. In this talk I will provide an outline of the classic high-pressure experiments that have traditionally been used to investigate and form such phases of both Si and Ge. I will further highlight how nanoindentation has been used to form the some technologically-interesting phases of these materials in a fabrication-friendly fashion.

Bio: Jodie Bradby completed her undergraduate degree at the RMIT before moving to ANU to commence a PhD on the mechanical properties of semiconductors. At the completion of her PhD she was awarded a Murdoch Education Fellowship that took her to Case Western Reserve University in Ohio. Jodie returned to Australia to take up an ARC postdoctoral fellowship at ANU and work closely with a startup company (Wriota) that was formed as a result of her PhD work. In 2009 Jodie was awarded a QEII fellowship by the ARC, secured tenure at the ANU in 2012 and was commenced an ARC Future Fellowship in 2014. She has a specific interest in coffee, phase transformations of semiconductors and a growing interest in the mechanical properties of biomaterials including corals and plant cells.
