April 2013 – Hydrogen dangling bonds are highly reactive and their selective exposure on hydrogenated Si(001) using scanning probes is developing as a powerful lithography to pattern molecules and atoms. We have found that hydrogen is more weakly bound along the centre of Haiku stripes, thus offering a new, fully scalable thermodynamic route to produce very long dangling bond rows in large numbers to self-assemble long chains of atoms and molecules. Our STM study further reveals an unexpected flat dimer configuration, possibly stabilized by the local strain induced by the Haiku core structure.

December 2012 - Congratulations to Dr. Maria Longobardi who has been elected as an International Student Affairs Officer of the American Physical Society. The ISA Officer chairs the International Student Affairs Committee. She will serve as the principal point of contact between the Forum and similar organizations in countries outside the United States and will act as a student advocate for international student issues to the American Physical Society. FGSA-sponsored international activities, including conferences and student issues, will be reported annually by the ISA Officer to both the FGSA Executive Board and the APS Director of International Affairs. Maria will serve a three-year term.
June 2012 – Measuring the piezoresistance in p-type silicon up to 3GPa, we found it to decrease with compressive stress beyond the predicted saturation. This result has potential implications for the Si technology roadmap. Collaboration with Ecole Polytechnique Palaiseau and IEMN. Article featured in
