Talk Title: 2D Materials, Devices and Systems â A New Paradigm for Electronics and Optoelectronics
Abstract: In the past eight years, the research community has seen rapidly growing interests in two-dimensional (2D) crystals and their applications. The 2D carrier confinement in this versatile family of materials - whose members range from the well-known semi-metal graphene to the insulator boron nitride, or the semiconducting layered transition metal dichalcogenides (LTMD) -
confers to them unique band structures with correlated electronic states where charge, spin, orbital, valley and lattice degrees of freedom play an important role in defining their exceptional properties of carrier transport, tunable bandgaps, mechanical strength, piezoelectricity, thermoelectric effects and their interactions with light. These materials, still in their infancy, carry great potential to redefine nano-electronics, optoelectronics and their interaction with biological systems in the coming years. In this talk, I will present my work on understanding the material synthesis, device technology, carrier transport and the forward-looking engineering efforts to develop electronic applications based on 2D crystals at the device and circuit level. I will conclude with remarks on how these new materials are expected to change energy generation, biological sensors, medical electronics at both device and system levels.
Biography: Han Wang received the B.A. and M.Eng. degrees in electrical and information science, both with highest honors, from Cambridge University, England, in 2007 and 2008. He is currently pursuing the Ph.D. degree in Electrical Engineering and Computer Science at Massachusetts Institute of Technology (MIT). In summer 2012, he held an internship at IBM T. J. Watson Research Center. His research interests include the synthesis, device technology and
novel circuit applications of two-dimensional (2D) materials â including graphene, hBN, MoS2, WS2, etc., and their heterostructures â with emphasis on exploring both the fundamental understanding and forward-looking applications of 2D materials in ubiquitous electronics, optoelectronics, energy efficient applications, and interaction with biological systems. His past research also includes GaN-based III-V HEMTs for high power millimeter-wave applications and Si power electronic devices.
His work has been recognized with multiple awards including Cambridge University Agilent Prize, IEEE IEDM Best Student Paper Award, International Conference on Compound Semiconductor Manufacturing Technology (CS MANTECH) Best Student Paper Award and numerous fellowships. Mr. Wang has authored or coauthored more than 40 publications in distinguished journals and conferences, 8 of them invited, 1 book chapter and 1 patent.

Talk Title: NanoEngineering for High Performance Devices and High Efficient Energy Systems
Abstract: In our everyday devices, about 60% of the primary energy is lost when converted from one form to another during operation. Nanotechnology holds the promise of dramatically improving device performance and energy efficiency. In this talk, I will discuss our efforts in engineering fundamental energy carriers at the nanoscale, in particular, for solid-state energy conversion, high-performance electronics and coherent quantum computation. First, I will present our recently developed hybrid nanostructures engineered to characterize nanoscale thermal transport. I will discuss how we can independently control the heat flow in a rationally designed path and selectively detect the local temperature. Coupling the system with ultrafast optical spectroscopy and modeling, we determined the mean free path dependent thermal conductivity in different materials. Our approach can serve as generic metrology for high throughput screening of energy materials and as a guidance tool for next-generation energy device design through phonon engineering. Second, I will present a novel material system achieved through bottom-up chemical synthesis and band structure engineering design. I will discuss our work in building high-performance electronics and integrated circuits, where the developed transistors outperformed the state-of-the-art MOSFETs and can also be applied for nano-bio interfaces. I will then talk about our development of a highly sensitive charge sensor integrated with coupled quantum dots, and show that we demonstrated full control and detection over charge dynamics, inter-coupling and lifetimes with GHz pulse manipulations. Finally, I will show that we developed the first long coherent Quantum Bit in Group-IV materials, which encodes information in the smallest energy quanta â⬓ spin, for next generation of efficient computation. We believe our efforts in developing new functional nanomaterials and structures will lead to advanced energy-conversion and device-operation paradigm in the future.
Biography: Yongjie Hu is currently the Battelle/MIT Postdoc Fellow in the Mechanical Engineering Department of the Massachusetts Institute of Technology with Professors Gang Chen and Mildred Dresselhaus, focusing on material optimization and device design for thermal transport and solar energy conversion. He obtained his M.A. (2006) and Ph.D. (2010) from Harvard University with a research focus in the areas of nanotechnology, including nanomaterials synthesis, structure characterization, high-performance devices and transport physics under the supervision of Professor Charles M. Lieber. Dr. Hu is a recipient of Micro & Nano: Heat Transfer Division Award from ASME (2012), Battelle/MIT Fellowship from MIT (2012), Chinaââ¬â¢s National Award for Outstanding Students Studying Abroad (2011) and Fieser Fellowship from Harvard University (2004, 2005).

CS Colloquium: Wyatt Lloyd (Princeton): Stronger Consistency and Semantics for Geo-Replicated Storage

Speaker: Wyatt Lloyd, Princeton
Talk Title: Stronger Consistency and Semantics for Geo-Replicated Storage
Series: CS Colloquium
Abstract: Geo-replicated storage systems provide the backend for massive-scale websites such as Google and Facebook. These storage systems seek to provide an always-on experience where every operation completes quickly because of a widely demonstrated link between page load times, user engagement, and revenue. We term systems that provide an always-on experience and can handle data at the required scale "ALPS"
systems because they provide four key properties: Availability, Low latency, Partition tolerance, and Scalability.
Previous ALPS systems made large usability sacrifices in pursuit of their scale and performance goals. They settled for eventually consistent replication between datacenters and inconsistent batch operations within them. My research shows that these sacrifices are not fundamental.
In this talk, I will present the first ALPS system to provide consistency that is stronger than eventual. Specifically, I will show how to provide causal consistency for data stored in multiple datacenters, each of which spreads the data across many servers. Then, I will show how to strengthen the semantics of that system with a richer data model as well as read-only and write-only transactions.
Biography: Wyatt Lloyd is a Ph.D. candidate in Computer Science at Princeton University. His research interests include the distributed systems and networking problems that underlie the architecture of large-scale websites, cloud computing, and big data. He received his masters degree in Computer Science from Princeton University, and a bachelors degree in Computer Science from Penn State University.
