The d parameters are a convenient parametrization for surface-related, quantum corrections. We establish a systematic approach to measure the d parameter dispersion of a general two-material interface.

Using a simple device structure, it has been shown that electrical control of optical properties can be achieved through electrochemical hydrogen gating, sourced from moisture in the air.
This unique partnership between Navajo Technical University and the Harvard MRSEC builds enduring pathways for undergraduate Native American students into STEM by including traditional Navajo perspectives and methods of scientific inquiry in materials science research and education.
A team at the Harvard MRSEC led by Lakshminarayanan Mahadevan and Jennifer A. Lewis has created shape-shifting lattices by combining predictive design and multimaterial 4D printing.
MXenes are two-dimensional (2D) ceramics made of transition metal carbides and nitrides. Unlike other 2D ceramics, MXenes have inherently good conductivity and thus are promising for various applications. Probing the local physical properties of MXenes monolayers is important for the understanding of their functional performance. Nebraska MRSEC researchers in collaboration with their colleagues at Drexel University have developed an improved method for synthesis of monolayer membranes of Nb4C3Tx MXene.
Nebraska MRSEC researchers have proposed a new concept to design high-performance ferroelectric tunnel junctions with enhanced tunneling electroresistance (TER). This design exploits property of a polar oxide material to create an ionic charge at the interface.
The Princeton MRSEC iSuperSeed focuses on the topics of polymeric materials driving structure and biological function at (i) the intracellular length scale, where recent observations of phase-separated liquid phases (left top image) are relevant to understanding responses inside cells, and (ii) extra-cellular length scales where porous material change shape or regulate run-and-tumble dynamics
Majorana zero modes (MZMs) can serve as building blocks for topologically protected quantum computers, promising scalable and fault-tolerant quantum computation platforms in the future. Princeton MRSEC investigators Ali Yazdani and B. Andrei Bernevig have realized a novel material platform based on the topological hinge state of bismuth.
The Zhu group developed a facile method to disassemble vdW single crystals layer by layer into monolayers with near-unity yield and with dimensions limited only by bulk crystal sizes (scheme shown on top). The macroscopic monolayers are comparable in quality to microscopic monolayers from conventional Scotch tape exfoliation.
Professor Theanne Schiros spoke to a full house of over 700 as part of a Sustainability Summit focused on the environmental impact of the fashion industry and positive solutions. She is in engaged in sustainable development for economic empowerment of women and artisans in Guinea and Cote d’Ivoire, providing trainings on natural dyes and biofabrication.
