ABSTRACT
Surface science has a long and distinguished history. As a discipline, it came into existence in the early 1970’s, but –like much of materials science- its origins go back quite a bit further, possibly to pre-historic times. In this talk I won’t go back quite so far, but start with the discovery of the electron by J.J. Thomson in 1897, and the elucidation of its wave properties by his son P.G. Thomson and by C.J. Davisson and L.H. Germer. While surfaces attracted much attention, the structure of silicon surfaces was still mostly a mystery as late as 1980. With a wave of new experimental techniques arriving in quick succession, just six years later an editorial in Science declared ‘Consensus on Silicon Surface Structure Near’. By the early 1990’s the problem of the atomic structure of surfaces, and its interplay with electronic, chemical, and magnetic properties was essentially solved (or at least solvable for each particular instance). I will discuss the industrialization of surface science since the 1990’s, and its impact on the field and on the broader world of science and technology today
BIOGRAPHY
Rudolf M. Tromp is a Research Staff Member at the IBM Thomas J. Watson Research Center, and a professor at Leiden University. His scanning tunneling microscopy studies revealed the Si(001) dimer structure for the first time, as well as the spatial distribution of the Si(111) (7 × 7) electronic surface states and their relation to the underlying atomic structure. Using Medium Energy Ion Scattering he co-invented “surfactant-mediated epitaxial growth,” a technique which allows improved control over the morphology of epitaxial films and superlattices. Using in-situ electron microscopy techniques, his studies have shed light on the thermodynamics of epitaxial growth, the dynamical evolution of epitaxial films, the self-assembly of quantum dots, the spatio-temporal character phase transitions at surfaces, etc. He has developed a novel Low Energy Electron Microscopy instrument, including energy filtering and aberration correction. Amongst other honors, he is the recipient of the MRS Medal, the APS Davisson-Germer Prize, and the AVS Medard W. Welch Award. He is the holder of 21 US and International Patents.
