“The chiral-chain van der Waals structure of tellurene gives rise to strong in-plane anisotropic properties and large thickness-dependent shifts in Raman vibrational modes, which is not observed in other 2D layered materials.”

Contrary to what you may think, this fragment was not written by AI, but by real researchers from Purdue University (USA) who have come up with a new material to make faster transistors with.

Tellurene is a two-dimensional crystal created from the rare element tellurium. Its special property that makes it interesting for use in electronics is the fact that electrons and holes move faster in it than in other materials. This property may be exploited to create faster transistors or smaller transistors that can switch higher currents.

Other important properties of tellurene are its stability at room temperature and the fact that it can be produced quite easily. Other tellurene-like two-dimensional materials, such as graphene, black phosphorus and silicene, are either not stable at room temperature or production in high quantities is difficult.

Also, compared to other 2D materials, tellurene crystals or flakes tend to be larger meaning less barriers in a tellurene semiconductor allowing it to carry higher currents.

Although tellurium is pretty rare, according to the researchers this is not a problem because only very small quantities are required.
