For example, one layer could allow
a fast flow of electrons through it, while the other type of layer could act as an insulator.
For example, while one layer of this new kind of superlattice can allow
a fast flow of electrons through it, the other type of layer can act as an insulator.

In 2011, the Hasan group detected this
fast electron -
flow in the interior
of a material made from combining several elements — bismuth, thallium, sulfur and selenium.
The first paper, published May 7, demonstrates that

The exquisite detail and continuous formation
of the radio images allowed the scientists to directly measure the speed
of the
fast electrons in the beam, marking the first time ever that the speed
of energy
flow in such a cosmic jet has been measured.
The
flow of electrons is
faster on graphene transistors than conventional transistors, which enables
faster data transfers between chips, Lin said.
I'm convinced that there's vast untapped potential to
fast forward progress by getting another billion or two

flow in novel ways at the speed
of electrons.
As I mentioned above, this is not hard to understand if you look at heat transport as a diffusion phenomenon, i.e., as
flow in accordance with the laws
of probability from a region characterized by a higher concentration (
of fast molecules or
fast electrons) to one with a lower concentration.
