Groundbreaking research on rhenium-based transition metal dichalcogenides reveals these materials respond to pressure in fundamentally different ways than other 2D semiconductors. The findings could enable new approaches to designing bulk devices with 2D functionalities for advanced electronics and photonics applications.

Unusual Pressure Response Discovered in Advanced 2D Materials

Researchers have uncovered surprising behavior in rhenium-based transition metal dichalcogenides (TMDCs) that distinguishes them from other two-dimensional semiconductors, according to recent reports. The study, published in npj 2D Materials and Applications, reveals that ReS₂ and ReSe₂ exhibit negative pressure coefficients for their main optical transitions—a characteristic opposite to what has been observed in other well-known TMDCs like MoS₂ and WS₂.
