SPINTRONIC! TRANSISTORS WITH QUANTUM MECHANICS

SEE JUST HOW IMPORTANT ROSWELL, 1947! TRANSISTORS HAVE BEEN

AND ARE EVEN INTO FAR REACHING FUTURE TECHNOLOGY!

Everything you touch your phone your laptop the  0:19

entire internet has been powered by transistors, tiny devices that rely on one fundamental property  

of electrons their charge, but what if I told you that's only scratching the surface and  

HUGE Breakthrough: Moving Beyond Electronics, Spintronics! 

now why do I say that manipulating a spin is such  a big deal because now in transistor technology  6:26

we are scaling beyond 2 nm and actually entering  ångström era and here things start to get really

weird because we bump into very strong effects of  quantum mechanics and one of the wildest effects

here is Quantum Tunneling it's when an electron  passes through a barrier

one  of the biggest limits as to how far we can keep 7:01

scaling the transistor technology but here is a  twist while shrinking breaks classical transistors

it actually helps spintronic devices because these  devices are built on this very effect so instead

of fighting Quantum Tunneling they are making use  of it

Japan found a way surprising way to do it with  lasers they found a way to control spin patterns 16:53

into a thin semiconductor layers using beams of  light imagine it like writing magnetic textures

with photons and this is a very promising step  towards a spin-based transistor
