Researchers have made atomically thin layers of five elemental metals by squeezing molten metal between molybdenum disulfide (MoS2)-coated sapphire components. The MoS2 layers encapsulate the metal, helping stabilize it at thicknesses of roughly six to nine ångströms. In the study, the standout electrical and vibrational measurements were made on bismuth—not on every metal in the set.
Why making a metal sheet this thin is difficult
Many familiar two-dimensional materials are crystals whose layers are held together weakly, so researchers can separate them into thin sheets. Elemental metals are harder to isolate this way: their atoms bond strongly in multiple directions, and an unsupported ultrathin layer can be difficult to stabilize. Zhao and colleagues’ 2025 study addresses both problems by confining molten metal between protective two-dimensional layers. The Nature paper describes the resulting interfaces as non-bonded, which helps researchers probe the metal’s properties.

How van der Waals squeezing makes the layers
The researchers place molten metal between sapphire components coated with single layers of MoS2, then squeeze the assembly. The confined metal forms an ultrathin layer, which remains encapsulated between the MoS2 sheets. This process is called van der Waals (vdW) squeezing.
The encapsulation is central to the method: the MoS2 layers surround and stabilize the thin metal while their non-bonded interfaces allow measurements of its properties. The study reports that pressure affected the likelihood of making monolayer bismuth. Its extended data says samples produced at 50 and 80 MPa were thick, while higher pressure increased the probability of monolayer formation. At 140 MPa, the researchers obtained bismuth monolayers larger than 100 μm. Those figures describe the paper’s experimental conditions, not a general recipe or guaranteed yield. Nature, 2025

Which metals were made, and how thin were they?
The paper reports five elemental metals at ångström-scale thicknesses. These are measured specimen values from the study, not fixed thicknesses that every sample of each element must have.
| Metal | Reported sample thickness |
|---|---|
| Tin | 5.8 Å |
| Bismuth | 6.3 Å |
| Lead | 7.5 Å |
| Indium | 8.4 Å |
| Gallium | 9.2 Å |
The Nature paper describes monolayer bismuth as about 0.64 nm thick, approximately 6.4 Å. Chemistry World characterizes the 6.3 Å bismuth sample as two atoms deep. Ångströms and nanometres are both length units: 10 Å equal 1 nm. Nature, 2025; Chemistry World, 19 March 2025

What unusual properties did the bismuth show?
The paper’s highlighted transport and Raman measurements focus on monolayer bismuth. The authors report a new phonon mode, enhanced electrical conductivity, a notable field effect and large nonlinear Hall conductivity. A phonon mode is a pattern of collective atomic vibration; Raman measurements can reveal such vibrational behavior. The reported results suggest that confining a metal to this thickness can change the electronic and vibrational behavior researchers observe.

What the results do—and do not—show
The work establishes a fabrication approach for ultrathin samples of several elemental metals and reports unusual measured properties in bismuth. It does not demonstrate a commercial product or a functioning quantum, electronic or photonic device. The authors identify those kinds of devices as possible future directions, so any practical application remains prospective.
Chemistry World reported that the bismuth sample remained stable for a year while researchers tested it. That durability detail is attributed to the publication’s reporting; it should not be read as a general lifetime guarantee for all metals or samples made by the method. Chemistry World, 19 March 2025

Why the method matters
Van der Waals squeezing offers a way to study elemental metals in a thickness regime that is difficult to reach with conventional isolation of layered crystals. Its importance is both the range of metals reported and the ability to encapsulate fragile ultrathin layers for measurement. The bismuth results give researchers specific electronic and vibrational phenomena to investigate next, while questions of broader reproducibility, device integration and useful operating conditions remain open.
