Dr Maarten Vos Australian National University
Brief career summary
Research Interests
At Flinders University I was involved in the first series of electron momentum spectroscopy (EMS) measurements using a spectrometer with two-dimensional detection techniques (e.g. Phys. Rev. B 50 5635 (1994), Phys. Rev B 51 3449 (1995), J. Phys. Condens. Matter 7 279 (1995)). The unified approach of EMS for the study of molecules and solids helped elucidate and illustrate the links between the electronic structure of both cases (Rev. Mod. Phys. 67 713 (1995), Am. J. of Phys. 65 544 (1967)). A simulation method to established effects of multiple scattering on the EMS data was developed (Phys. Rev. B 54 5946 (1996)). It became obvious that EMS data could only be described correctly by models going beyond a mean-field level (J. Phys. Condens. Matter 11 3654 (1999)). A new spectrometer was designed and constructed at the ANU, based on the Flinders experience, aiming to reduce multiple scattering (Rev. Sci. Instrum. 71 3831 (2000)). This made a more quantitative study of the many-body effects possible (Phys. Rev. B 65 033108 (2001). Phys Rev. B. 66 155414 (2002)). The quality of the electron optics of the ANU spectrometer was so good that it revealed the effects of vibrations in elastic (not EMS) scattering spectra (Phys. Rev. A 65 012703, Phys. Rev. Lett. . 91 057403 (2003)).
