Atomically-Thin Heterostructures for Electronic and Photonic Applications

The isolation of a growing number of two-dimensional (2D) materials has inspired worldwide efforts to integrate distinct 2D materials into van der Waals (vdW) heterostructures. While a tremendous amount of research activity has occurred in assembling disparate 2D materials into “all-2D” van der Waals heterostructures, this concept is not limited to 2D materials alone. Given that any passivated, dangling bond-free surface will interact with another via vdW forces, the vdW heterostructure concept can be extended to include the integration of 2D materials with non-2D materials that adhere primarily through noncovalent interactions. In the first part of this talk I will present our work on emerging mixed-dimensional (2D + nD, where n is 0, 1 or 3) heterostructure devices. I will present our ongoing and recent work on integration of 2D materials with 3D semiconductors to realize novel, gate-tunable devices with record performances. I will present the underlying charge transport and photocurrent responses in both the above systems using a variety of scanning probe microscopy techniques as well as estimation of band alignments using computational methods.

The second part of talk will discuss my more recent work on photonic structures and photovoltiac devices from 2D semiconductors such as transition metal dichalcogenides (TMDCs). High efficiency inorganic photovoltaic materials (e.g., Si, GaAs and GaInP) can achieve maximum above-bandgap absorption as well as carrier-selective charge collection at the cell operating point. Similar opportunity exists for 2D chalcogenide semiconductors towards which we have made progress by light trapping in < 15 nm thick TMDC layers. I will present the fabrication and performance of our, broadband absorbing, heterostructure photovoltaic devices using sub-15 nm TMDCs as the active layers, with record high quantum efficiencies and open circuit voltages for high power conversion efficiences. I will then extend the concept of light trapping in TMDCs to explore fundamental light-matter interactions including observation of novel and tunable hybrid states. If time permits I will present our ongoing efforts on in-situ electron beam and near-field imaging of low-dimensional materials and heterostructures. I will conclude by giving a broad perspective of future work on 2D materials from fundamental science to applications.

Matthew Stamm

Matthew C. Stamm is an Associate Professor in the Electrical and Computer Engineering Department at Drexel University.  He heads the Multimedia and Information Security Laboratory (MISL) where he and his students conduct research on signal processing, machine learning, and information security.  Much of his research focuses on multimedia forensics, which involves developing techniques to detect multimedia forgeries such as falsified images and videos.  His research has been funded by the NSF, DARPA, the Army Research Office, the Defense Forensic Science Center, and the Defense Forensics and Biometrics Agency.

Dr. Stamm is the recipient of a 2016 CAREER Award from the National Science Foundation and Drexel University’s 2017 College of Engineering Outstanding Early-Career Research Achievement Award.  He was the General Chair of the 2017 ACM Workshop on Information Hiding and Multimedia Security and the lead organizer of the 2018 IEEE Signal Processing Cup competition. He currently serves as a member of the IEEE SPS Technical Committee on Information Forensics and Security and as a member of the editorial board of IEEE SigPort.

Dr. Stamm earned his B.S., M.S., and Ph.D. degrees in Electrical Engineering from the University of Maryland, College Park in 2004, 2011, and 2012 respectively.  For his dissertation research, he was awarded the Dean’s Doctoral Research Award in 2012 from the A. James Clark School of Engineering at the University of Maryland. Additionally, Dr. Stamm worked as a radar systems engineer at the Johns Hopkins University Applied Physics Laboratory from 2004 until 2006.

Multimedia Forensics – Using AI to Detect Image and Video Forgeries

Multimedia content such as images and video play a critical role in today’s society. It is used by news agencies during reporting, as evidence during criminal investigations, and as intelligence in many military and defense scenarios.  At the same time, an information attacker can easily falsify multimedia content using “deepfake” software or editing tools such as Adobe Photoshop.  This presents a major problem for society – How can we combat misinformation if it is so easy to fake multimedia content?

In this talk, I will discuss several algorithms to detect image and video forgeries using deep learning that we have developed here at the Multimedia and Information Security Lab (MISL) at Drexel. Instead of relying on extrinsic security measures such as cryptography, these techniques identify evidence of editing and falsification by exploiting traces intrinsically left in digital media by editing operations. Additionally, I will discuss how multimedia forensic techniques can determine the source of an image by utilizing traces left in an image by its source camera.  These traces can be used as a trustworthy alternative to unreliable or easily falsifiable information sources such as metadata.

Inverter Dominated Dynamic Microgrids with Interdependencies in Cyber and Physical Systems

Grid modernization has raised the increasing interests in power system resiliency enhancement. As the penetration level of distributed energy resources (DERs) increases rapidly, a distribution grid, as the active and most significant ‘grid-edge’ for DER integration, plays a crucial role to bridge the grid backbone (i.e., transmission system) to the end-users. A resilient, stable and secure distribution system is urgently needed to modernize electric grids and ensure operation continuity. As an effective entity of integrating DERs and local loads, microgrids have been widely deployed in modern distribution grids. In addition to single and individual microgrids, networked and dynamic microgrids with controllable and effective interconnections have been deployed and studied to advance resiliency enhancement, especially for critical infrastructures. Given the information exchange to ensure stable control and physical interactions between neighboring microgrids, networked and dynamic microgrids can be regarded as coupled cyber and physical systems with interdependencies across layers. In this presentation, a cross-layer and resilient control framework of networked and dynamic microgrids with stability guarantees will be discussed. Particular examples and use cases will also be introduced to verify the proposed control framework.

Everything Old Is New Again: The Value of Historical Research in Science and Engineering

Studying the origins of a field and studying the evolution of discoveries and developments is certainly a satisfying intellectual endeavor.  In practical terms, it has often been the case that we find understanding how our predecessors saw things sheds new light on current techniques.  Furthermore, new perspectives are one of the best sources of new developments.  In this talk, we look at recent research into the design and development of the ENIAC and at what it can tell us about current and future computer design.  Was the ENIAC a controversial sidebar of history, or was it the prototype of modern microarchitectures, FPGAs, and a new approach to realizing the power of Turing’s model?
