Chinese researchers have made a significant breakthrough in materials science by successfully producing the world's first large sheets of single-atom-layer metals, with a thickness only one two-hundred-thousandth the width of a human hair.
This achievement, published on Wednesday by a team from the Chinese Academy of Sciences' Institute of Physics in the prestigious science journal Nature, marks a major milestone in the study of two-dimensional (2D) metals.
Most materials seen in people's daily lives are three-dimensional that have length, width, and height. When one of these dimensions is reduced to an atomic scale, the material becomes two-dimensional.
For example, a single sheet of paper, appearing incredibly thin to the naked eye, can be loosely considered as a 2D material. But under magnification, it still has some measurable thickness.
In scientific terms, true 2D materials are just one or a few atoms thick, roughly one-millionth the thickness of a paper.
To create the 2D metal, the research team melted bismuth at a temperature of 280 degrees Celsius and applied an original technique called van der Waals (vdW) squeezing. Over several hours, a single-atom-layer metal is yielded.
"Here's a single-atom-layer 2D bismuth metal created via our vdW squeezing technique. To observe it clearly, we placed it under an optical microscope, which magnified the sample about 1,000 times. The bismuth is encapsulated by a single layer of molybdenum disulfide, with the darker color indicating the presence of the bismuth metal sample in the middle," said Du Luojun, a distinguished researcher with the Institute of Physics.
The team has already successfully produced five types of 2D metals including bismuth, tin and lead, paving the way for transformative applications in multiple cutting-edge fields.
"2D metals hold immense potential for future applications. For example, it can be used in potential application scenarios including application in miniaturized devices, quantum information processing and storage, or ultra-sensitive detectors. They could also serve as wiring or other core materials for chips," said Zhang Guangyu, another researcher at the institute.
