Study may contribute to the feasibility of transistors with electrical currents consisting of the passage of one single electron at a time, with applications for future computers.

Laser light is used in the microscopic circuit to cool clouds of lithium atoms to temperatures near absolute zero. Once the atoms are slowed, the researchers can then hold them in place, move them ...

In solar cells, solar radiation boosts electrons to higher energy states, thereby releasing them from their atomic bonds as electricity begins to flow. Scientists have now developed a novel method ...

In a circuit connected to a battery, the electrons are the charge carrier and flow from the battery’s negative terminal, around the circuit and back to the positive terminal.

An electron will not pass through every component on its way round the circuit. If one of the bulbs is broken then current will still be able to flow round the circuit through the other loop.

A very thin Graphene layer, when twisted at a proper angle, forms a new material called Intercrystal, showing signs of electronic behaviour.

A study showing how electrons flow around sharp bends, such as those found in integrated circuits, has the potential to improve how these circuits, commonly used in electronic and optoelectronic ...

Here, we use such a technique to observe electron flow through a narrow constriction in a 2DEG—a quantum point contact.

The phenomenon represents a milestone in the emerging field of ‘atomtronics’, which seeks to create a whole new class of devices that use the flow of atoms, rather than electrons, in a circuit.

I came to engineering by way of the technician route. I learned electronics in a technical school and was taught that current flow was electron flow and all circuit analysis was done that way.

If you want an electrical current to flow around a normal metal ring you have to supply enough energy to overcome the metal’s resistance – right? Not always, according to physicists in the US and ...
