Nebraska Quantum Materials Research Grant $2.5M EPSCoR
A US$2.5 million DOE EPSCoR grant has boosted the University of Nebraska–Lincoln.
Nebraska Quantum Materials Research Faster With Grant
This funding infusion will build infrastructure and human resources for emergent quantum phenomena and enhance frontier quantum materials research.
It supports UNL's quantum materials research goals and is the third significant funding for the Emergent Quantum Materials and Technologies (EQUATE) Centre in recent months.
Ferroelectric Oxides and Interface Redesign
The grant's main focus is a study led by UNL physics and astronomy professor Xia Hong and a team of seven. Ferroelectric oxides, oxide, and van der Waals materials will be used to create quantum phases hitherto unattainable.
The team wants nanoscale control of ferroelectric processes in thin-film oxides to generate novel states of matter, such as reversibly switching between metal and insulator or magnetic and non-magnetic states. Hong said the goal is to use nanoscale ferroelectricity control to create a new state of matter to design smaller, more energy-efficient devices.
There are three main thrusts:
Exploring the potential for reversible quantum phase transitions (metal ↔ insulator; magnetic ↔ non-magnetic) at ferroelectric oxide and strongly-correlated oxide boundaries.
Integrating ferroelectric insulators into polar metals and multiferroic systems to store low-energy data by transitioning magnetic states with electric fields.
Ferroelectric thin-film superlattices and 2D van der Waals materials are stacked, rotation angles (Moiré engineering) adjusted, and domain structures altered to engineer new electrical and optical properties.
If successful, new smartphone and memory/logic device platforms may use less energy and perform better.
Infrastructure and Workforce: Two Investments
Besides science, the DOE EPSCoR award prioritises team training and infrastructure development. The two-year project may be extended to four years.
The project will fund early-career scientists at both schools and cooperate with South Dakota School of Mines & Technology. Early-career academics include Alexey Lipatov (SDSMT), Tula Paudel (SDSMT), and Zuocheng Zhang (UNL). Undergraduates, post-docs, and graduate students will participate.
“EPSCoR is looking into infrastructure and human resource development, not just research,” Professor Hong said.
The organisation intends to establish a long-term quantum materials science centre in the Midwestern US by improving its tools and workforce.
Nebraska's Quantum Materials Hub Gains Momentum
This grant builds on previous financing. Nearly five years ago, the NSF gave UNL $20 million to build the EQUATE Centre.
UNL researchers have obtained a $2 million NSF “Designing Materials to Revolutionise and Engineer Our Future” (DMREF) Grant and a $1.8 million NSF EPSCoR grant to develop innovative two-dimensional (“flatland”) materials.
Nebraska is becoming a quantum materials leader by focussing energy-efficient gadgets, next-generation electronics, and innovative materials research. This method is backed by multi-institution coalitions, academic leadership, and funding.
Expanding Technology and Society Implications Although the work focused on materials science and difficult physics, the implications are vast. Effective teamwork may yield:
High-efficiency devices that reduce computer power consumption.
Quantum-phase transitions replace semiconductor switching to provide quicker, smaller, and more powerful logic and memory systems. New 2D and oxide-membrane materials with programmable electrical and magnetic responses could revolutionise consumer electronics, memory storage, sensors, and quantum technologies.
A better regional quantum training and research environment for workforce readiness and new field innovation.
Hong said, “Even though you may not immediately see the impact, you are motivated by curiosity, the beauty of nature, and the fascination with how things behave.” That's the beauty of basic science.
What to Watch Next
The UNL team will focus on the three research thrusts' important milestones in the following years. Success will likely be measured by realistic device prototypes, scalable manufacture of new layered materials, and reversible quantum-phase switching demonstrations. Progress will also be shown by infrastructural growth and scientific training.
Based on its momentum and funding, Nebraska's EQUATE Centre might become a premier centre for quantum materials and devices, contributing to the national quantum information science, advanced electronics, and sustainable computing movement.
UNL hopes to lead quantum materials research with this $2.5 million investment and turn theoretical quantum phenomena into practical gadgets that could boost technology.
