"“Towards Molecular Electronics:
Solution-Based Methods for Selective Deposition of Metals and Semiconductors”
Dr. Amy V. Walker, UT Dallas
Robust methods for the chemically selective deposition of metals, semiconductors, biomolecules and other substances are developed and applied in the construction of complex two- and three-dimensional structures. This work has important applications in molecular and organic electronics, sensing, biotechnology and photonics. These methods are easily parallelized, afford precise nanoscale placement and are compatible with photolithography. Three examples are discussed in detail: the electroless deposition of Cu and the chemical bath deposition (CBD) of CdSe on functionalized self-assembled monolayers (SAMs), and the formation of Ni nanowires on micron-scale patterned surfaces.
Amy Walker is an associate professor of materials science and engineering at UT Dallas. She obtained her BA (Hons) and PhD (with Prof. David King) at the University of Cambridge. She was subsequently a postdoctoral scholar with Prof. John Yates Jr. (the University of Pittsburgh) and then with Prof. Nick Winograd (Pennsylvania State University). Prior to joining UT Dallas she was an assistant professor of chemistry at Washington University in St. Louis. She has published more than 50 papers in refereed journals in addition to two book chapters, and she has given more than 40 invited talks at universities, international conferences and companies. She has received a number of awards and honors, including an Oak Ridge Associated Universities Ralph E. Powe Junior Faculty Enhancement Award (2003), a DuPont Young Professor Award (2006) and an ACS/PROGRESS lectureship (2008). She is the chair elect and member-at-large of the Applied Surface Division of the AVS and a member of the International Committee on SIMS.
