Now, we're currently in between with almost all the communist/republican countries.
Ever since Donald trump came in president. Things got a bit rough with China and the U.S
There might be a war soon WWIII.
Based on this, Individual electrons in graphene have almost no mass compared to the other particles.
The material graphene consists of a single layer of carbon atoms arranged in a hexagonal lattice.
Electrons flowing through graphene can be scattered from impurities (such as foreign atoms in the lattice), from other electrons and from lattice vibrations known as phonons.
What happens to the electrons in graphene?
According to the researchers, such high values are a result of the photo thermoelectric effect. “It turns out that when you shine a light on graphene, the electrons in the material heat up, and remain hot, while the underlying carbon lattice remains cool,”
Why are electrons massless in graphene?
Yes, low energy electrons and holes in graphene can be thought of as massless because of the linear dispersion of the band structure near the K points.
This is an analogy to the relativistic energy dispersion E2=P2C2+M2C4, which becomes linear in momentum for m=0.
