Tutorial S.EL09—Phase-Change Memory—Materials Fundamentals and Advanced Applications


Instructors: Matthias Wuttig, RWTH Aachen University; Wolfram Pernice, University of Münster; Riccardo Mazzarello, RWTH Aachen University; Fabio Pellizzer, Micron Technology, Inc.

The rapidly growing demand for data storage and processing, driven by artificial intelligence (AI) and other data-intensive applications, is posing a serious challenge for current computing devices based on the von Neumann architecture. For every calculation, data sets need to be shuffled sequentially between the processor, and multiple memory and storage units through bandwidth-limited and energy-inefficient interconnects, typically causing 40% power wastage. Phase-change materials (PCMs) show great promise to break this bottleneck by enabling nonvolatile memory devices that can optimize the complex memory hierarchy, and neuro-inspired computing devices that can unify computing with storage in memory cells. In this tutorial session, four comprehensive talks are scheduled to highlight recent breakthroughs in the fundamental materials science, as well as electronic and photonic implementations of these novel devices based on PCMs.

2020 MRS Fall Meeting Tutorial Sessions

Tutorial F.GI01—The Biology and Pathology of COVID-19—An Immunology Primer


Instructors: Bryan Bryson, Massachusetts Institute of Technology

The SARS-CoV-2 pandemic has quickly spread throughout the globe in 2020. As such, engineers have applied their knowledge in materials design to approach prevention of infection, testing to diagnose infections, and treatment after an individual has COVID-19. These advancements rely on an understanding of the basic biology of SARS-CoV-2 from virology to immunology.

Tutorial F.EL02—Novel Perovskite Compounds as Classical and Quantum Light Sources


Instructors: Bin Hu, University of Tennessee; Gabriele Raino, ETH Zürich

This tutorial will focus on fundamental science involved in emerging light-emitting materials and device-halide perovskites, quantum dots and other nanoscale emitters. Currently, the efforts on materials processing and device engineering have led to significant developments on light-emitting properties in spontaneous and coherent regimes at different length and time scales. However, it is recognized that further advancing the light-emitting properties of hybrid halide perovskites, quantum dots, and nanoscale emitters requires a deeper understanding of the fundamental processes involved in the carrier recombination. Essentially, the fundamental science can provide the critical understanding and experimental approach to effectively control light-emitting properties in these emerging materials under spontaneous and coherent regimes. Therefore, the fundamental science have become a crucial task in the research and development of emerging light-emitting materials. This tutorial will present the latest results on the photophysics involved in emerging light-emitting materials, unveiling their specifics down to the single particle/photon level.

Tutorial F.NM02—Optical Metasurfaces—Materials, Designs and Advanced Applications


Instructors: Mark Brongersma, Stanford University; Igal Brener, Sandia National Laboratories; Harry Atwater, California Institute of Technology; Jonathan Fan, Stanford University

Metasurfaces are arrays of subwavelength anisotropic light scatters (optical antennas) that can produce abrupt changes in the phase, amplitude or polarization of light. Within the last few years, there has been significant progress on the design of metasurfaces that refract and focus light, enabling many unique properties and applications such as holograms, optical vortex generation/detection, ultrathin focusing lens, perfect absorber, etc.

Tutorial F.NM06—Spin Dynamics in Materials for Quantum Technologies—Experiment and Theory


Instructors: Mikhail Glazov, Ioffe Physical-Technical Institute, RAS; Michael Flatté, The University of Iowa; Bernhard Urbaszek, CNRS – Toulouse University; Anaïs Dreau, Laboratoire Charles Coulomb, University of Montpellier

Over the past decades the research focused on materials with controllable spin and valley polarization dynamics has moved from the realm of fundamental research towards applications. This progress is due to the development of new techniques and tools in experiment and theory and access to new material systems. Examples include magnetometry with NV centers sensitive to a single spin or to magnetic domains in a single atomic layer. Another example is confocal microscopy coupled to single photon detectors analyzing the recombination of a single electron hole pair. These experimental insights are closely linked to progress in our theoretical understanding.  For example, the crystal structure of the functional materials and the polarization states of the electrons and photons coupled in these systems can be precisely accessed and their evolution can be predicted by theory. These experimental and theoretical tools are now widely used to uncover the properties of new classes of materials such as ferromagnetic van der Waals materials and single defects implanted in crystals. This tutorial aims to give an introduction on how we access spin dynamics in materials for quantum technologies in both experiment and theory. We introduce the main concepts and tools and outline the interesting challenges in material research that lie ahead in order to harness the spin degree of freedom for potential applications.
