> The polycrystalline tin selenide the team makes is spiked with sodium atoms, creating what is known as a “p-type” material that conducts positive charges. To make working devices, researchers also need an “n-type” version to conduct negative charges.
This is literally inventing half a solution. Shockley didn't go to the press when he'd built half a diode.
(OK, this is snarky, but I think this is another case where people need to understand the difference between "a small but valid advancement in the art" and "actual products". As a materials science paper this is valid.)
