SUMMARY:Molecular Clusters: Building Blocks for Nanoelectronics and Materia
 l Design - Xavier Roy (Columbia University)
DESCRIPTION:Molecular Clusters: Building Blocks for Nanoelectronics and Mat
 erial DesignXavier RoyChemistry DepartmentColumbia University
\nAbstract: 
 The programmed assembly of nanoscale building blocks offers exciting new a
 venues to creating electronic devices and materials in which structure and
  functions can be chemically designed and tuned. In this context\, the syn
 thesis of inorganic molecular clusters with atomically-defined structures\
 , compositions and surface chemistry provides a rich family of functional 
 building elements. This presentation will describe our efforts to assemble
  such “designer atoms” into a variety of hierarchical structures and d
 evices\, and study the resulting collective properties. In one design\, si
 ngle clusters are wired into electrical junctions that can be operated as 
 molecular-scale transistors. The single cluster devices exhibit room-tempe
 rature current blockade below a threshold voltage\, and they can be “tur
 ned on” by applying an electrochemical potential across the junction\, e
 nabling the temporary occupation of the cluster core states by sequential 
 transiting carriers. A second area of exploration is in creating solid sta
 te materials in which preformed clusters emulate the role of atoms in trad
 itional “atomic” solids. These materials offer a unique opportunity to
  combine programmable building blocks and atomic precision. As such\, they
  bridge traditional crystalline semiconductors\, molecular solids\, and na
 nocrystal arrays by synergizing some of their most attractive features. Re
 cent synthetic advances to develop this concept into a “modular” platf
 orm for materials design will be presented. It will be shown that novel\, 
 tunable\, collective properties (magnetic\, optical\, electrical and therm
 al transport) emerge from specific interactions between the building block
 s within these assemblies.
\nBio: Xavier Roy received a B.Eng. (2002) and 
 a Master of Applied Science (2005) in Chemical Engineering from Ecole Poly
 technique of Montreal\, performing research under the guidance of Prof. Ba
 sil Favis. He earned his Ph.D. in Chemistry with Prof. Mark MacLachlan at 
 the University of British Columbia in 2011\, working as an NSERC Alexander
  Graham Bell Scholar. He went on to do postdoctoral research as a Canada N
 SERC Postdoctoral Fellow with Prof. Colin Nuckolls at Columbia University 
 from 2011 to 2013. He joined the Columbia University Faculty in 2013 as an
  Assistant Professor of Chemistry\, and was promoted to the rank of Associ
 ate Professor in 2018.
