Coulomb blockade is a phenomenon in which the flow of electrons through a nanostructure, such as a quantum dot or a single-electron transistor, is restricted due to the electrostatic repulsion between ...

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 ...

Scientist have found they can turn on and off the flow of current in a bismuth crystal subjected to a high magnetic field, making a new type of controllable quantum wire. Princeton researchers have ...

Electrons flow through most materials more like a gas than a fluid, meaning they don’t interact much with one another. It was long hypothesized that electrons could flow like a fluid, but only recent ...

Harvard John A. Paulson School of Engineering and Applied Sciences Electrons flow through most materials more like a gas than a fluid, meaning they don’t interact much with one another. It was long ...

Crystalline materials known as topological insulators conduct surface current perfectly, except when they don't. In two new studies published in the journal Science, researchers explain how these ...
