so we can design around them

it's more about understanding the failure modes

but also no

so now we can make better leds?

that's actually useful

they can see how the leds degrade over time

oh right

like why does this matter

wait what's the actual breakthrough here

or a secret government lab

probably some rich university somewhere

who even has machines that good

like sub-nanometer or something

also the resolution is insane

but still

i mean i get the basic idea...

how is that even possible

wtf

like individual defects in the crystal structure

it's wild how much detail they're getting

found this paper on arXiv

idk

but for science

so it's like a tiny flashlight torture chamber

genius

and watch the light that comes back out

basically they shoot electrons at leds

lol

it's called something like cathodoluminescence microscopy

okay so this new imaging method...
