Gentle reminder [cid:image001.jpg@01D7B5D1.3327AEF0] The BNC Faculty Seminar Series is designed to provide faculty a platform to present an overview of their research and the opportunity for collaborative discussion with other BNC faculty and researchers across six colleges and 15 academic units. Arun Kumar Mannodi Kanakkithodi Assistant Professor, School of Materials Engineering, Purdue University September 30th, 2021 | 12:00pm Join Zoom: https://purdue-edu.zoom.us/j/98695180597 [Arun Kumar Mannodi Kanakkithodi]Title: Tuning Optoelectronic Properties of Semiconductors using High-Throughput Computations and Machine Learning Abstract: Semiconductors with desirable electronic band structure and optical absorption are sought for solar cells, electronic devices, infrared sensors, and quantum computing. Compositional manipulation via alloying at cation or anion sites, or via incorporation of point defects and impurities, can help tune the properties of semiconductors in known chemical spaces. In this work, we develop AI-based frameworks for the on-demand prediction of the phase stability, band gap, optical absorption spectra, photovoltaic figures of merit, defect formation energies, and impurity energy levels in two broad classes of semiconductors, namely (a) halide perovskites with the general formula ABX3 (where A is a large organic or inorganic monovalent cation, B is a divalent cation and X is a halogen anion), and (b) group IV, III-V and II-VI semiconductors in the zinc blende structure. These frameworks are powered by high-throughput density functional theory (DFT) computations, unique encoding of the atom-composition-structure information, and rigorous training of advanced neural network-based predictive and optimization models. Multi-fidelity learning is applied to bridge the gap between (high quantities of) low accuracy calculations and (lower quantities of) high-fidelity data, constituted of data from advanced DFT functionals. AI-based recommendations are synergistically coupled with targeted synthesis and characterization, leading to successful validation and discovery of novel compositions for improved performance in solar cells. Bio: Arun Mannodi Kanakkithodi is an assistant professor in Materials Engineering at Purdue university. He received his PhD in Materials Science and Engineering from the University of Connecticut in 2017 and worked as a postdoctoral researcher at the Center for Nanoscale Materials in Argonne National Laboratory from 2017 to 2020. His research involves using first principles computational modeling, machine learning, and materials informatics to drive the design of new materials for energy-relevant applications.

Reminder: BNC Faculty Seminar Series: Speaker - Ryan Wagner - September 23rd | 12noon | via Zoom
by Black, Nancy Lee 23 Sep '21

23 Sep '21

Sorry for my sending a second reminder. [cid:image001.jpg@01D7B05B.E6748F30] The BNC Faculty Seminar Series is designed to provide faculty a platform to present an overview of their research and the opportunity for collaborative discussion with other BNC faculty and researchers across six colleges and 15 academic units. Ryan Wagner Research Assistant Professor, School of Mechanical Engineering September 23rd, 2021 | 12:00pm Join Zoom: https://purdue-edu.zoom.us/j/98695180597 [cid:image004.jpg@01D7B05F.BA28D9A0]Title: Vibrations and mechanics applied to Multiphysics problems in MEMS, Manufacturing, and Microscopy Abstract: At the macroscale, microscale, and nanoscale vibrations and mechanics can be exploited for metrology in process monitoring, system design, and diagnostics. In this talk, I will discuss three vibration and mechanics based metrology problems across these three length scales. At the macro-scale, roll-to-roll systems enable scalable manufacturing of flexible electronic devices. The magnitude and distribution of web tension can have a significant effect on device yield and performance. To address this, we have developed a vibration-based metrology system for measuring the tension distribution within the web substrate. At the microscale, microcantilever-based radio frequency capacitance switches are an important MEMS device. Stiction failure, where the cantilever becomes stuck to the dielectric surface is an important failure mode. We used the Atomic Force Microscope (AFM) as a surrogate system for studying the dynamic detachment of a microcantilever from a surface. This is a possible recovery mechanism for fixing failed devices. At the nanoscale, the detailed modeling of viscoelastic contact mechanics is important for simulating the interactions between an AFM cantilever tip and soft, viscoelastic surfaces. Commonly employed models for this are often ad-hoc in nature leading to inconsistent predictions of surface behavior. We have developed a computationally improved implementation of Attard’s model, a rigorous first principles contact mechanics model that enables accurate prediction of surface dynamics for soft, viscoelastic materials. We have deployed this model in our online AFM simulation tool VEDA, which is found on nanoHUB.org. Bio: Ryan Wagner is a Research Assistant Professor in the School of Mechanical engineering at Purdue University. He received his B.S. and Ph.D. both in Mechanical Engineering from Purdue in 2008 and 2014 respectively. His graduate research topic was the application of AFM to study the mechanics of cellulose-based nanomaterials. Ryan was awarded a National Research Council postdoctoral fellowship at the National Institute of Standards and Technology where he worked on AFM metrology and cavity optomechanics. After this postdoc, Ryan was employed as a Research and Development Scientist at Asylum Research, an AFM instrument manufacturing company. Ryan’s research interests include metrology, microscopy, interferometry, spectrometry, vibrations, and dynamics.
