Local labs working towards making computing more energy efficient

Title: Powering Progress: Labs Team Up to Make Computing Greener and Tougher

In the digital age, our world is increasingly powered by silicon, from smartphones to smart homes. But as artificial intelligence (AI) becomes ubiquitous, so does the energy demand. Enter Sandia and Los Alamos National Laboratories, joining forces to make computing more energy-efficient and resilient to extreme environments.

The U.S. Department of Energy, under the Biden Administration, has invested $179 million to establish three microelectronics research centers, including two where Sandia and Los Alamos are key players, with Sandia co-founding one. These centers are tackling society’s most pressing questions as we hurtle towards a fully digitized world.

"Everything has a computer chip in it now," says Jeffrey Nelson, director of the Center for Integrated Nanotechnologies (CINT), a Sandia-Los Alamos collaboration. "Even our refrigerators and toasters are saying they have chips."

But this digital revolution comes at an energy cost. AI’s proliferation will only exacerbate the demand, Nelson warns. "All of the demands on the energy system will just increase as AI is proliferated in our society."

Researchers are exploring alternative materials like molybdenum disulfide, gallium arsenide, and diamond to replace silicon in certain applications. "We’re trying to think about new material options that will help reduce those energy demands," Nelson explains. These materials, with their low resistance or suitability for communications, could significantly reduce energy consumption.

Meanwhile, there’s a growing need for computer chips that can withstand harsh environments, from outer space to nuclear reactors. Jennifer Ann Hollingsworth, a Los Alamos scientist, is working on making building block materials more radiation-resistant and components more reliable in extreme conditions.

These collaborative efforts, backed by federal funding, promise a wealth of new materials, devices, and technologies. Nelson envisions economic opportunities for New Mexico, attracting research and investment, and potentially spawning new companies.

As we continue to digitize our world, Sandia and Los Alamos are at the forefront, ensuring our progress is powered responsibly and resiliently.
