The lecture will be on Tuesday, November 27, 2018, in lecture hall Ke 2 (Chemistry building, Kemistintie 1), at 10:00-11:00. Welcome!

Prof Barry has been working with CVD and ALD reactant synthesis for well over a decade, and has been visiting labs such as Harvard University (Prof Roy Gordon) and University of Helsinki (Professors Leskelä and Mikko Ritala). Laboratory website link: https://carleton.ca/barrylab/

Title: “Precursors and Atomic Layer Deposition of Gold Metal” 

Abstract:

Gold metal is an important thin film material for enhanced spectroscopy, meta-material fabrication, plasmon-based sensing, and catalysis. Since it was first reported in 2016, deposition of gold metal by atomic layer deposition has rapidly progressed to encompass several processes using energetic co-reagents, and the mechanism of deposition has been studied to determine how the process is initiated and to improve precursor and process performance.  As well, the design of gold-containing precursors represents a delicate balance of inter- and intra-molecular forces to produce a stable but volatile species. Analysis of these forces in the solid state can provide insight into the thermodynamics of volatilization, and might predict how to control it better. An in-depth analysis of a family of potential gold precursors, and the interplay of forces that hold them together, will be presented along with an update on deposition using the known ALD precursors for gold.
