Accelerating Materials Innovation: Rapid-Cycle Fabrication, Measurement, and Discovery


Overview

The Autonomous Discovery and Laser Self-driving Labs are dedicated to accelerating materials discovery by successfully closing the "predicting, measuring, making" discovery loop. These facilities have the unique capability to generate high-quality data from high-speed measurements, which are used to train the machine learning models that are an integral part of the closed feedback loop. This research has critical implications for national security, driving funded efforts to create new materials that manipulate the electromagnetic spectrum to close the THz gap, enabling improved infrared sensors, better materials and filters, and other remote sensing technologies for applications in space and satellites. Additional applications include new improved materials and electrodes for cooling in data centers, batteries, thermal energy storage, and more.

Why a Laser Self-driving Lab?

The Laser Self-driving Lab uses lasers to rapidly change and measure material properties (topology) in seconds. A new sample is produced every few seconds to minutes, and to date 120,000 samples have been generated.
