Professor Ignatius Mcgovern
Fellow Emeritus, Physics

Biography

I have been in the Physics Department at Trinity College since 1979; previously I held research positions in the University of Wisconsin, University of Pennsylvania and the New University of Ulster.

I am married to Eileen Patten and we have a son, Eoin.

My main extracurricular activity is creative writing; a first collection of poetry 'The King of Suburbia' was published in late 2005 by Dedalus Press

Research Expertise

Description

My general area of research is Surface Physics, specifically the photoelectron spectroscopy of semiconductor surfaces using synchrotron radiation. My principal interest has been in the adsorption of small molecules on clean, ordered semiconductor surfaces; the area has a connection with device processing. More recently, research has focused on organic molecule adsorption. Synchrotron radiation has a unique combination of properties of intensity, tunability, polarisation and time-structure; when applied to traditional spectroscopy such as photoelectron spectroscopy, there is both a quality enhancement and the opportunity to p[erform novel variations on the technique, such as 'near-edge absorption fine structure ' or NEXAFS and 'photoelectron diffraction' or PhD
