Prof. Jing Kong
(MIT, USA)
Presentation Title
Synthesis and Integration of 2D materials for Device Applications
Date & Time
09:30 – 10:30, June 29 (Mon.)
Biography
Jing Kong received her B.S degree in Chemistry from Peking University, Beijing, China in 1997 and PhD degree in Chemistry from Stanford University in the United States, 2002. In 2004, she joined the faculty at MIT, where she is currently Professor in the Electrical Engineering and Computer Science Department. She has worked in the field of carbon nanotubes since 1997 and has published numerous papers on this subject. In MIT, this research has led to the synthesis of related nanostructures such as graphene and later graphene-like two dimensional materials. The current research activity in her group involves CVD synthesis, characterization of these low dimensional materials, investigation of their electronic and optical properties and developing their applications.
Lecture Summary
Two dimensional (2D) materials have attracted a lot of interest due to their remarkable properties and great potentials, especially for the integrated circuits and future computing applications. Their successful applications rely critically on their synthesis and integration process development. In this talk, I will present our investigations for these via two complementary approaches, i.e. low temperature (compatible with BEOL) synthesis for direct integration vs. high temperature synthesis combined with transfer process. Both chemical and physical vapor deposition (CVD, PVD) approaches were explored for the synthesis development. These studies will help identifying suitable strategies to integrate 2D materials in the future electronics and computing applications.

Lecture Summary
Advanced electronic/optoelectronic systems built using classes of nanomaterials that enable intimate integration with living
organisms will accelerate progress in biomedical research; they will also serve as the foundations for new approaches in
monitoring and treating diseases. Specifically, capabilities for injecting miniaturized electronic elements, light sources,
photodetectors, multiplexed sensors and other components into precise locations of soft tissues or for softly laminating them
onto the surfaces of vital organs will open up unique and important opportunities in tracking and manipulating biological
processes. This presentation describes concepts in materials science and assembly techniques that underpin these types of
technologies, including bioresorbable, or ‘transient’, devices designed to disappear into the body on timescales matched to
natural processes. Examples include skin-like devices for health monitoring, ‘cellular-scale’ optofluidic neural probes for
optogenetics research and bioelectronic ‘medicines’ for accelerated regeneration of damaged peripheral nerves and temporary
cardiac pacing.

Lecture Summary
The rapid scaling of artificial intelligence (AI) has exposed fundamental limitations in the energy efficiency and throughput of conventional von Neumann architectures. Memristors offer a compelling hardware-level solution. This talk reviews recent advances in memristive materials, devices, and computing architectures, highlighting how emerging materials enhance memristive devices to accelerate AI workloads and enable neuromorphic computing.
The presentation begins with an overview of memristor fundamentals, including physical mechanisms, programmability, and robustness under extreme environments. It then examines memristor-based AI accelerators, focusing on in-memory computing architectures that perform vector–matrix multiplication directly within memristive arrays, reducing data movement and improving deep-learning efficiency.
Finally, the talk explores neuromorphic computing enabled by intrinsic memristor dynamics, which support native synaptic and neuronal functions and enable brain-inspired AI systems that remain difficult to realize efficiently with purely digital hardware.

Lecture Summary
Over 50 years ago Halperin and Hohenberg [1] predicted that certain magnetic systems behave analogously to liquid Helium. In this talk I will describe some of our recent work that uses NV center magnetometry to explore spin excitations in layered magnets. By employing different measurement modalities we are able to directly observe signatures of magnon hydrodynamics and magnon second sound which is analogous to second sound in superfluid liquid Helium. Finally by directly detecting coherent spin waves we are able to devise a new scattering platform for exploring mesoscopic magnetism.

Lecture Summary
I will discuss the benefits of vacuum processing of metal halide perovskite semiconductors for their use in photovoltaic devices. I will report on the progress on vapor phase deposited perovskites, including novel low vacuum based deposition methods such as close-space and vapor transport sublimation. In-situ monitoring of the photoluminescence during the deposition of the perovskite enables us to learn about their specific growth mechanism. We use this to study the effect of seeding layers on the perovskite growth which helps us to achieve high quality films that lead to solar cells with efficiencies above 23 %.
I will also discuss the benefit of using these perovskites in substrate configuration as well as semitransparent cells for bifacial operation and for building integrated PV. The use of sublimed perovskite in perovskite-silicon tandem cells using fully textured Si bottom cells will be presented, including methods to identify the shortcomings of these tandem cells. I will also comment on the performance of these cells under accelerated stress conditions and under outdoor stressing.

Lecture Summary
Free electrons in a semiconductor are usually described by weakly interacting Fermi liquid that conducts electricity. However, Wigner pointed out 90 years ago that Coulomb interactions become dominant at low electron density and low temperature, resulting in the formation of the electron solid, known as the Wigner crystals. Atomically thin two-dimensional (2D) semiconductors and heterostructures offer a highly tunable platform for exploring the electron solid phases. In this talk, I will describe our effort to directly image the Wigner crystal and its quantum melting behavior in atomically thin semiconductors using scanning tunneling microscopy. I will also discuss a rich variety of Wigner solid behaviors that can emerge when one- and two-dimensional potentials are imposed on atomically thin semiconductors and when the electron becomes anisotropic.
