Students calculate wavelength, frequency, or the velocity of a wave. Atomic Theory: Electrons on the Atom Bohr’s model of the atom are described. Students calculate wavelength, frequency, or the ...

When physicists search for new semiconductors for chips or lasers, they have been able to rely on sophisticated computer programs - until now. However, it is possible that the models these programs ...

The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...

Making electrons flow like a liquid is difficult, but inside graphene researchers forced them to move so fast that they ...

Yet even at this apparently late date in the field's development, there are companies that are still developing entirely new qubit technologies, betting the company that they have identified something ...

A single-electron transistor with a central component -- an island only 1.5 nanometers in diameter -- that operates with the addition of only one or two electrons has been developed. The transistor, ...
