MAESTRO is one among dozens of X-ray beamlines at the ALS that are specialized for samples ranging from proteins and vaccines to batteries and meteorites.

In addition to MAESTRO’s precise measurements, the careful preparation of the tungsten disfulfide flakes in sufficient size for study, and their transfer to a base material (substrate) that didn’t impede their electronic properties or obstruct the X-ray measurements were also vital in the success of the latest study, Jozwiak noted.

Jyoti Katoch, the study’s lead author and a research scientist at The Ohio State University, said, “Two-dimensional materials are extremely sensitive to their surroundings, so it’s imperative to fully understand the role of any outside disturbances that affect their properties.”

Katoch worked with Roland Kawakami, a physics professor at Ohio State, in preparing the samples and designing the experiment. They coupled samples of WS2 to boron nitride, which provided a stable, non-interacting platform that was crucial for the X-ray measurements. Then they used a metal as an “external knob” to modify the properties of the WS2.

“This study enables two critical breakthroughs: it provides a clear fundamental understanding of how to remove outside effects when measuring the intrinsic properties of 2-D materials, and it allows us to tune the properties of 2-D materials by simply modifying their environment.”

Søren Ulstrup, an assistant professor at Aarhus University who had worked on the WS2 MAESTRO experiments as a postdoctoral researcher, added, “Seeing the intrinsic electronic properties of the WS2 samples was an important step, but perhaps the biggest surprise of this study emerged when we started to increase the number of electrons in the system – a process called doping.

“This lead to the dramatic change of the splitting in the band structure of WS2,” he said, which suggests the presence of trions.

MAESTRO can handle very small sample sizes, on the order of tens of microns, noted Rotenberg, which is also a key in studying this and other 2-D materials. “There’s a big push to resolve materials’ properties on smaller and smaller scales,” he said, to better understand the fundamental properties of 2-
