PRISM/PCCM SEMINAR SERIES FALL 2016 POSTER

Sep 14, 2016  ·  9:00 a.m. 6:00 p.m.  ·  Bowen Hall Auditorium

Seminar 9/28/2016 - Chunlei Guo, University of Rochester: Surface Functionalization with Femtosecond Lasers

Sep 28, 2016  ·  12:00 p.m. 1:00 p.m.  ·  Bowen Hall Auditorium

Abstract: Femtosecond laser materials processing is a rapidly advancing field due to its high precision and versatility. In this talk, I will discuss a number of techniques developed in my lab that allow us to functionalize material surfaces through femtosecond laser processing. The techniques led to the creation of the so-called black and colored metals, brighter incandescent light sources, superhydrophillic and superhydrophobic surfaces. Possible applications of the functionalized materials will also be discussed.

Bio: Chunlei Guo is a Professor in The Institute of Optics and Department of Physics & Astronomy at University of Rochester. He also directs a newly established Center for Laser Material Processing. His research is in the area of femtosecond laser-matter interactions. He received his Ph.D. in Physics from University of Connecticut and a postdoctoral training at Los Alamos National Laboratory. His work at Rochester has led to the discoveries of a range of highly functionalized materials, which may find a broad range of  applications and have been featured extensively by the media, including 4 New York Times features. He is a Fellow of American Physical Society and Optical Society of America. Currently, he serves as the Editor-in-Chief for one of the most widely used handbooks in lasers and optics, CRC Handbook of Laser Technology and Applications (2nd Edition).

All seminars are held on Wednesdays from 12:00 noon-1:00 p.m. in the Bowen Hall Auditorium Room 222. A light lunch is provided at 11:30 a.m. in the Bowen Hall Atrium immediately prior to the seminar.

Seminar 10/5/2016 - Zahra Fakhraai, University of Pennsylvania: Measuring Long-range Correlated Dynamics in Amorphous Systems

Oct 5, 2016  ·  12:00 p.m. 1:00 a.m.  ·  Bowen Hall Auditorium

Abstract: Nanometer-sized thin films of small organic molecules are widely used in applications ranging from organic photovoltaics and organic light emitting diodes, to protective coatings and high resolution nano-imprint lithography. Physical vapor deposition (PVD) is widely used in manufacturing ultra-thin layers of amorphous organic solids, with an underlying assumption that the properties of these layers are bulk-like. Here, we demonstrate that films of organic glass-formers with thicknesses of 30 nm or less have dynamics significantly enhanced relative to the bulk at temperatures well below the glass transition temperature, Tg. Furthermore, we show that a sharp glass to liquid transition exists when the thickness of the layer changes from 40nm down to 20nm. While these measurements are important for a host of applications, they can also help elucidate the fundamental mechanisms of glass transition temperature, a question that has attracted numerous theories in the past half century. Specifically, we are able to show that glassy systems have long-range correlated dynamics that can well exceed their inter-molecular interaction range. 

All seminars are held on Wednesdays from 12:00 noon-1:00 p.m. in the Bowen Hall Auditorium Room 222. A light lunch is provided at 11:30 a.m. in the Bowen Hall Atrium immediately prior to the seminar.

Seminar 10/19/2016 - Chris Bowman, University of Colorado

Oct 19, 2016  ·  12:00 p.m. 1:00 p.m.  ·  Bowen Hall Auditorium

Title and abstract to follow.

Bio: Professor Christopher N. Bowman is currently the Patten Endowed Chair of the Department of Chemical and Biological Engineering, the Director of the Materials Science and Engineering Program, and a Distiguished Professor at the University of Colorado. He received his B.S. and Ph.D. in Chemical Engineering from Purdue University in1988 and 1991, respectively. After receiving his Ph.D., he began his academic career at the University of Colorado in January of 1992. Since that time Professor Bowman has built a program focused on the fundamentals and applications of crosslinked polymers formed via photopolymerizations and click reactions. Professor Bowman has published nearly 350 refereed papers and been recognized with awards from the American Chemical Society, the American Institute of Chemical Engineers, the Materials Research Society, and the Society for Biomaterials.  His research involves the synthesis of novel monomers and the implementation of various photoinitiated polymerization reactions in a range of applications including adhesives, coatings, dental materials, photolithography, nanotechnology and biomaterials.

All seminars are held on Wednesdays from 12:00 noon-1:00 p.m. in the Bowen Hall Auditorium Room 222. A light lunch is provided at 11:30 a.m. in the Bowen Hall Atrium immediately prior to the seminar.

Seminar 11/9/2016 - Shelby Nelson, Eastman Kodak: Thin-film Electronics by Spatial ALD

Nov 9, 2016  ·  12:00 p.m. 1:00 p.m.  ·  Bowen Hall Auditorium

Title: Thin-Film Electronics by Spatial ALD - Achieving High Performance with Low Process Complexity

Abstract: Patterning thin-film transistors for 'printed electronics' applications can be challenging both for resolution and for alignment accuracy. This is particularly true for high-performance devices with submicron channel lengths, and for diverse and deformable substrates. Printing organic-based devices requires additional consideration of issues such as printing dynamics and orthogonality of solvents.  In this talk, I will describe alternative approaches to scalable thin-film electronics based on spatial atomic layer deposition (SALD) of metal oxides. Using the relatively high deposition speed of SALD, the conformality of the deposited layers, and the surface-sensitivity of the technique, we have explored both print-compatible high-performance vertical transistors, and patterned-by-printing circuitry. A reliable ZnO mobility above 10 cm2/Vs, on-off ratio above 107, and uniform threshold voltage values across the substrate give these approaches promise for large-area applications.
