01 Apr '13

Purdue University School of Chemical Engineering Graduate seminar series Prof. Paul Nealey Institute of Molecular Engr., University of Chicago "Directed Assembly of Block Copolymers on Lithographically Defined Chemically Nanopatterned Substrates" April 2, 2013 9:00-10:20 a.m. FRNY G140 Reception at 8:30 a.m. in Henson Atrium Abstract: The use of block copolymers in the lithographic process is an attractive strategy to augment and enhance the capabilities of current tools in nanomanufacturing. We employ electron beam and 193 nm immersion lithography to fabricate chemically patterned surfaces. Block copolymer films are deposited on the surfaces and annealed. By judicious choice of the chemistry and the geometry of the patterned regions, the domain structure of the block copolymer film may be directed to assembly into desirable architectures for applications such as bit patterned media or integrated circuits. Challenges that remain in materials and process development include delineation of the degree of perfection that can be obtained, and fabrication of sub 10 nm features in manufacturing-relevant processes. Here we report 1) the relationships between attributes of the chemical pattern and the degree of perfection of the assembled block copolymer films, 2) two approaches to processing films on chemical patterns to enable assembly of high resolution copolymers with differing block surface energies, and 3) design principles for the synthesis of new block copolymers for directed self-assembly with sub 10 nm features. Bio: Paul F. Nealey is currently the Brady W Dougan Family Professor in Molecular Engineer-ing at the new Institute for Molecular Engineering of the University of Chicago. His research interests include nanofabrication techniques based on advanced lithography and directed self-assembly, development of imaging materials for alternative lithographic strategies, and dimension dependent material properties of nanoscopic macromolecular structures. He is a fellow of the American Physical Society, and has received the National Science Foundation Career Award, the Camille Dreyfus Teacher-Scholar Award, the University of Wisconsin Romnes Fellowship, the Nanoscale Science and Engineering Forum Award from the American Institute of Chemical Engineers, and the Arthur K. Doolittle Award from the American Chemical Society. He was also the Founding Director of the National Science Foundation-funded Nanoscale Science and Engineering Center in Templated Synthesis and Assembly at the Nanoscale.

FW: CoE Inaugural Faculty Colloquium - Joseph Pekny; 3:30 pm Today!
by Varma, Arvind 29 Mar '13

29 Mar '13

Dear Colleagues, I write to echo Jim Litster's note below, and to provide some additional background. As follow up of the team that Jim co-chaired, the ELT approved a process to "...recognizing the achievements of senior faculty... this process includes providing continual professional development, supported by thoughtful planning and goal setting, as part of academic professional life for all faculty, at all stages in their careers. The hope is that such a program will support faculty in their plans to build on their successes and expand their horizons, as well as leverage the valuable experience and capabilities of senior faculty who may want to take on new roles at the university." To implement the program, in January this year, all CoE Heads were requested to provide names of at most 2 of their School's faculty, who fit the following criteria: 1. Full Professors who have been at that rank at least 7 years or more, or joined Purdue as a full professor 2. Faculty of different career paths and vision, i.e., it would be preferable if both nominees did not have the traditional research based careers. I nominated two ChE faculty, one with a "traditional research based career" and Joe as one in a "different career paths and vision." Among all the nominees, the CoE selected 3 faculty members whose careers are being celebrated this semester - Joe is in this inaugural group. With this, he brings recognition to himself and to our School! As noted below, the seminar details are: Friday, March 29, 2013 3:30 p.m. seminar, Forney Hall of Chemical Engineering, Room G124 4:30 p.m. reception, Forney Hall, Henson Atrium Pl attend, to celebrate Joe's outstanding career, which has unlimited future potential! Best, Arvind Arvind Varma R.

[JOSEPH F. PEKNY] JOSEPH F. PEKNY<https://engineering.purdue.edu/Engr/AboutUs/Administration/AcademicAffairs/…> "Knowledge Acquisition Frameworks and Deliberate Innovation - Perspectives from and Next Steps for a Journey in Engineering Complexity"<https://engineering.purdue.edu/Engr/AboutUs/Administration/AcademicAffairs/…> We live at a time of marvelous advances and great promise. For example, many of us wear and make phone calls with handheld "computers" that dwarf the capability of supercomputers of just a few years ago. The fundamental advances responsible for such a Moore's law phenomena will drive profound and unpredictable economic improvements for many years. Yet, people are aware that our society is up against what might perhaps be existential challenges. Climate change, economic bubbles, terrorism, affordability of healthcare, cancer, national debt, providing sufficient energy for everyone, etc. are challenges of incredible complexity. How can we reconcile scientifically these observations of great promise and foreboding challenge? At least partially, our society has reached the limits of understanding that are possible through scientific reductionism. Observations of complexity over the last few decades show that new principles are required for useful understanding. I will use the experiences from my career at Purdue to provide a practical definition of complexity and introduce the developing ideas of knowledge acquisition frameworks and deliberate innovation as tools which can mitigate complexity. These tools may prove useful to understanding and engineering the "holistic" nature of complexity.

FW: Solar Seminar Series April 4, 2013 #:30 PM BNC Rm 2001
by Murray, Chris L 26 Mar '13

26 Mar '13

From: Black, Nancy Lee Sent: Tuesday, March 26, 2013 12:46 PM Subject: Solar Seminar Series April 4, 2013 #:30 PM BNC Rm 2001 Please post and distribute to all whom may be interested. thanks Kurt R. Mikeska Birck Rm. 2001 April 4, Thurs., 3:30 p.m. "Crystalline Silicon Solar Cell Metallization" Crystalline silicon solar cell technology has advanced by improvements to all aspects of cell design including metallization. Improvements to metal contacts have been synergistic with other cell improvements such as passivation, lightly doped emitters, and boron doped emitters. Recent improvements in metallization contacts have allowed the solar cell industry to move from highly doped emitters (HDE), designed to enable sufficiently low contact resistance, to lightly doped emitters (LDE), which have much lower recombination velocities, lower saturation current and improved cell efficiency. We will discuss both accepted theories and new insights into silver-silicon contact mechanisms, which combined have led to recent improvements in cell design and performance. Kurt R. Mikeska received his Ph.D. in Materials Science and Engineering from Rutgers University, College of Engineering and is currently a Senior Research Associate at DuPont in the Central Research and Development Department, Experimental Station, Wilmington DE. His expertise is in solid state inorganic synthesis, and he has worked in the area of crystalline silicon photovoltaics for the past ten years developing contact metallizations and investigating metal-semiconductor interface contact mechanisms. He has over 25 granted patents and 40 publications. Any questions please call, Nancy Black Secretary Birck Nanotechnology Center West Lafayette, IN 47907-2057 Phone: 765-494-8675 Fax: 765-494-4731
