The era of computing technologies based on charge currents is coming to an end after more than  40 years of exponential increases in computing power and data storage that have been largely based on shrinking devices in two dimensions.  A new era of “Beyond charge!” will evolve over the next decade that will likely be based on several new concepts. Firstly, devices whose innate properties are derived not from the electron’s charge but from spin currents and from ion currents.  In some cases new functionality will arise that can extend charge based devices but in other case fundamentally new computing and data storage paradigms will evolve.  Secondly, devices will inevitably become three-dimensional: novel means of constructing devices, both from bottom-up and top-down, will become increasingly important. Thirdly, bio-inspired devices that may mimic the extremely energy efficient computation systems in the biological world are compelling.  In this talk I will discuss possible nascent spintronic and ionitronic materials and devices and how they may lead to novel computing and data storage technologies over the next decade or so.


Stuart Parkin is the Managing Director of the Max Planck Institute for Microstructure Physics, Halle, Germany, and an Alexander von Humboldt Professor, Martin Luther University, Halle-Wittenberg. His research interests include spintronic materials and devices for advanced sensor, memory, and logic applications, oxide thin-film heterostructures, topological metals, exotic superconductors, and cognitive devices. Parkin’s discoveries in spintronics enabled a more than 10000-fold increase in the storage capacity of magnetic disk drives. For his work that thereby enabled the “big data” world of today, Parkin was awarded the Millennium Technology Award from the Technology Academy Finland in 2014 (worth 1,000,000 Euro). Parkin is a Fellow/ Member of: Royal Society (London), National Academy of Sciences, National Academy of Engineering, German National Academy of Science – Leopoldina, Royal Society of Edinburgh, Indian Academy of Sciences, and TWAS – academy of sciences for the developing world and has received numerous awards from around the world.

“Characterization of Atomic Scale Lattice Reconstruction in Twisted van der Waals Interfaces of Layered Materials

Presented by Professor Philip Kim, Physics, and Applied Physics, Harvard University

Friday, May 17, 2019
4:00pm, B11 Kimball Hall
Refreshments at 3:30pm, 116 Upson Hall

Control of the interlayer twist of van der Waals (vdW) interfaces has been widely used to engineer an artificial 2-dimensional (2D) electronic systems by the formation of a moiré superlattice. Many exotic physical phenomena occur associated with the incommensurability of the moiré superstructures where the wealth of the nontrivial topology of electronic band structures plays a key role to create exotic physical phenomena. In this presentation, we will discuss the engineered atomic scale reconstruction at twisted vdW interfaces using electron microscopy, optical spectroscopy, and electrical transport. We then will discuss emerging electronic and optoelectronic physics in the vdW interface between homojunctions.

Professor Philip Kim received his B.S. in physics at Seoul National University in 1990 and received his Ph.D. in Applied Physics from Harvard University in 1999. He was Miller Postdoctoral Fellow in Physics from University of California, Berkeley during 1999-2001. He then joined in Department of Physics at Columbia University as a faculty member during 2002-2014. Since 2014, he moved to Harvard University, where he is a Professor of both Physics, and Applied Physics.

The focus of Prof. Kim’s group research is the mesoscopic investigation of transport phenomena, particularly, electric, thermal and thermoelectrical properties of low dimensional nanoscale materials. These materials include carbon nanotubes, organic and inorganic nanowires, 2-dimensional mesoscopic single crystals, and single organic molecules.

Professor Kim has received numerous honors and awards including the Oliver E. Buckley Prize (2014) from American Physical Society.

“Integrated χ(2) Photonics”

Presented by Professor Hong Tang, School of Engineering & Applied Physics, Yale University

Refreshments at noon

Abstract: The ability to generate and manipulate photons with high efficiency and coherence is of critical importance for both fundamental quantum optics studies and practical device applications. However mainstream integrated photonic platforms such as those based on silicon and silicon nitride lack the preferred cubic χ(2) nonlinearity, which limits active photon control functionalities. In this talk, I will present integrated photonics based on aluminum nitride (AlN), whose wurtzite crystal structure gives rise to the strong second-order optical nonlinearity and piezoelectric effect. Together with its low optical and mechanical losses, the integrated AlN photonics can provide enhanced χ(2) photon-photon interactions to achieve high fidelity photon control, including on-chip parametric down-conversion, coherent light conversion, spectral-temporal shaping, and microwave-to-optical frequency conversions.

This event is hosted by the School of Electrical and Computer Engineering and by the Kavli Institute at Cornell for Nanoscale Science.



2018 Kavli Prize Laureates Announcements:

Live webcast and Program: http://www.kavliprize.org/

May 31st 8:30-10:00am EDT/2:30-4pm CEST

Keynote speaker: Honorable Shirley Ann Jackson Ph.D., President, Rensselear Polytechnic Institute

Watch the live webcast of the 2018 Kavli Prize laureate announcements by the Norwegian Academy of Science and Letters in Oslo, Norway, and live coverage of a special Prize program from the World Science Festival in New York City, including a special keynote address by the Honorable Shirley Ann Jackson Ph.D., President, Rensselaer Polytechnic Institute. 

The Kavli Prize recognizes scientists for pioneering advances in our understanding of existence at its biggest, smallest, and most complex scales. Presented every two years in the fields of astrophysics, nanoscience and neuroscience, each of three prizes consists of USD $1 million. Laureates are nominated by committees whose members are recommended by The Chinese Academy of Sciences, The French Academy of Sciences, The Max Planck Society (Germany), The National Academy of Sciences (US), The Royal Society (UK) and the Norwegian Academy of Science and Letters. From these nominations, The Norwegian Academy of Science and Letters selects the laureates.

First awarded in 2008, the Kavli Prizes have so far honored 47 scientists from 11 countries – France, Germany, Japan, Lithuania, The Netherlands, Norway, Russia, Sweden, Switzerland, the United Kingdom and the United States. Winners receive gold medals in Oslo, Norway, in a ceremony presided over by His Majesty King Harald. A banquet takes place at Oslo’s famed City Hall. The Kavli Prize is a partnership between the Norwegian Academy of Science and Letters, The Kavli Foundation (USA) and the Norwegian Ministry of Education and Research.
