A Superatomic Semiconductor Sets a Speed Record (quantum.columbia.edu)

Columbia University chemists have developed Re6Se8Cl2, a superatomic semiconductor exhibiting ballistic flow, potentially surpassing conventional semiconductors in speed and efficiency.
This material forms acoustic exciton-polarons that move scatter-free across the material, promising faster and more efficient energy and information transfer.
Unlike silicon, exciton-polarons in Re6Se8Cl2 pair with phonons, enabling steady, rapid movement without scattering, which could lead to faster processing speeds at room temperature.
Re6Se8Cl2 is unlikely for commercial use due to the rarity and cost of Rhenium, but the discovery opens possibilities for other materials with similar properties for future technological applications.

They appear to be attempting to give it a distinct name here.

Rather than scattering when they come into contact with phonons, excitons in Re6Se8Cl2 actually bind with phonons to create new quasiparticles called acoustic exciton-polarons. Although polarons are found in many materials, those in Re6Se8Cl2 have a special property: they are capable of ballistic, or scatter-free, flow. This ballistic behavior could mean faster and more efficient devices one day.

It definitely is a distinct name, searching for it pretty much only brings up articles about their study.
