A $1.5 million Defense Department award will boost materials science and quantum technology research at the University of Iowa. The MATFab facility will be modernized by purchasing high-resolution lithography and printing tools for nanoscale structures using this financing. Innovative sensors and quantum devices for national defense and environmental monitoring are being developed by combining physics, chemistry, and engineering skills. The project offers students and faculty specialized training and collaborative possibilities to build the university as a regional innovation hub beyond technical advancement. Researchers need cutting-edge tools to compete in nanofabrication; this investment ensures that.

A Hub for Interdisciplinary Innovation
The Materials Analysis, Testing, and Fabrication (MATFab) Facility is at the center of this complex project. MATFab was created in 2019 by the Office of the Vice President for Research (OVPR) with the goal of centralizing the university’s activities in micro-nanofabrication. The facility, which today occupies 1,500 square feet of clean room space within the Iowa Advanced Technology Laboratories, is positioned to develop into a major regional center for the development of new materials.
This project brings together physics, chemistry, and engineering experts. Because quantum research requires multiple scientific perspectives, this multidisciplinary approach is essential to understanding how materials can be employed to build light- or electronic-based quantum systems.

Overcoming the Challenges of the Nano-Scale
There are obstacles in the way of advancing quantum technology. The fact that materials react differently at the micron and nanoscale is one of the main issues. One of the biggest challenges for researchers is to comprehend the distinct benefits of materials, both separately and in combination.
This will be addressed by replacing “aging equipment” that has proven harder to maintain with DoD cash. The antiquated infrastructure had previously made it difficult for faculty and students to carry out innovative research, according to Tori Forbes, Director of MATFab and a professor in the Department of Chemistry. The new equipment will guarantee that the upcoming generation of scientists can be trained on cutting-edge instruments, enabling ongoing innovation.

The ‘Nano-Sandwich’ and the Laser Pen
Purchasing advanced fabrication systems is the upgrade’s main technical component. The most important addition is a grayscale lithography technology that does not require a mask. In essence, this technology functions as a “laser pen,” enabling researchers to sketch intricate three-dimensional forms, like domes, onto surfaces.
This system has a resolution as low as 300 nanometers, according to the award’s primary investigator, assistant professor Ravitej Uppu of the Department of Physics and Astronomy. Extremely delicate designs that can vary in height in relation to the surface can be created thanks to this accuracy.
The institution will also purchase printing equipment that allows researchers to layer or stack materials. This procedure is similar to making a “nano-sandwich”. Scientists may optimize the optical and electrical properties of materials by layering them in this manner, transforming conceptual designs into practical, operational devices. These gadgets range from small transistors essential to quantum computing to light-routing components.
Practical Uses and National Security
This study has ramifications that go well beyond the lab. The potential for these new materials to improve defense and national security capabilities is the foundation of the DoD’s interest. Some such uses are:
- Improved Remote Sensors: New materials may lead to sensors that more accurately detect contaminants in drinking water.
- Advanced Mapping: Military personnel could get a significant edge from the technology by being able to create maps of battle areas more quickly and with greater precision.
The goal of quantum sensing is to develop sensors with better picture quality and sensing capabilities by utilizing the features of quantum mechanics.
A Regional Educational Epicenter
The University of Iowa plans for MATFab to function as a focal point for the larger academic community in the area in addition to its research objectives. Faculty and students from a variety of Iowa colleges and institutions will be able to take use of the new equipment’s capabilities.
A summer workshop is already planned to teach students from local institutions how to utilize these cutting-edge fabrication machines. To promote cooperative initiatives and guarantee that the local workforce is proficient in the newest technology, this program seeks to create a “bridge” between institutions.
