Rather, phonons, which we can think of as "heat particles," are the result of collective vibrations of the material's atoms, and they tend to diffuse, with microscopic collisions that don't ...

It’s the interactions between phonons and electrons that cause electrons to slow down, or their momentum to relax. It’s the reason why electrical resistance of conductors decreases at a lower ...

A condition long considered to be unfavorable to electrical conduction in semiconductor materials may actually be beneficial in 2D semiconductors, according to new findings by UC Santa Barbara ...
