If anyone is interested in how this new material is made: it’s literally grown from scratch.
Imagine a 3D printer at atom scale. But because the scale is so small, the nozzle has to deposit a gas.
The magic is in making the individual gas molecules get to the right place.
Layer by layer, to what theory predicted would be a light emitting configuration.
Incredible achievement.

- jpmattia 7y agoMOVPE is more of a self-assembly process than 3D printing, and it has been around for decades. BTW It is worth noting from your link that the silicon is being grown on a GaAs substrate, so to be useful they would have to figure out how to grow the silicon wire on a silicon substrate. (GaAs already has many options for optical devices.)
