Three Heron group projects receive combined $900k+ in funding

The new funding gives a boost to the Heron group's goals of designing otherwise unstable complexes in correlated oxides, advancing transformative performance in memory and logic devices, and realizing chemically identical yet electronically distinct nanoscale thin film superlattices of materials.

Schematic of a five cation entropy stabilized oxide in a rocksalt structure. Local distortions from differing cation sizes and unfavored stereochemistry lead to new bond lengths and bond angles creating new interplay for correlated materials.

Project #1: MRSEC: Center for Nanoscale Science

Award: $630,000; part of $18M total funding for the Center for 6 years from NSF

Project Summary: We will explore uncharted territory in entropic materials discovery space to realize atypical chemical environments in oxides. We seek to design otherwise unstable complexes in correlated oxides for metal-insulator transitions and spin Hall effects.

Project Collaborators: 
Vin Crespi (Penn State University), PI

 

Project #2: Non-volatile Magnetoelectric Switching of a Nanomagnet Below 250 mV and 100 aJ Dissipation Through Enhanced Thin Film Magnetostriction

Award: $262,500

Project Summary: This project seeks to address the need for non-volatile memory and logic devices with 10-100x lower energy dissipation than CMOS utilizing pioneering developments in magnetostrictive materials by the Heron group. Here we will study magnetoelectric performance from micro to nanoscales in our composite multiferroic to realize transformative performance in memory and logic devices while elucidating fundamental scaling laws in ferroic switching.

 

Project #3: High entropy oxide metamaterials for control of high-temperature radiative heat transfer

Award: $14,000 of $150,000 funding for Phase 1 from DARPA

Project Summary: In this project we will precisely control thermodynamic conditions during physical vapor deposition to realize chemically identical yet electronically distinct nanoscale thin film superlattices of materials only stabilized by configurational entropy. We leverage the solubility and stability of entropic hosts to realize novel photonic structures for suppression of high temperature radiative transfer.
