(Phys.org) —The integrated circuits in virtually every computer today are built exclusively from transistors. But as researchers are constantly trying to improve the density of circuits on a chip, ...

Logic operations – such as NOT, AND, OR and XOR – are carried out in existing electronic circuits by semiconductor devices including diodes and transistors. But the density of electrons flowing ...

(Phys.org) —It was a busy week for applied physics as Researchers build first 3D magnetic logic gate—they used programmable 3D nano-sized magnets to build the gate–it could lead to circuit chips with ...

lectrical engineers at the Technische Universität München (TUM) have demonstrated a new kind of building block for digital integrated circuits. Their experiments show that future computer chips could ...

Electrical engineers have demonstrated a new kind of building block for digital integrated circuits. Their experiments show that future computer chips could be based on three-dimensional arrangements ...

We’ve seen NAND and NOR logic gates – the building blocks of everything digital – made out of everything from marbles to Minecraft redstone. [kos] has outdone himself this time with a logic circuit we ...

Energy efficient nanomagnetic logic (NML) computing architectures propagate binary information by relying on dipolar field coupling to reorient closely spaced nanoscale magnets. Signal propagation in ...

Year after year, semiconductor manufacturers scale down the size of components, making processors faster and more efficient. However, we're approaching the limits of atomic scale with silicon, leading ...

Theoretical physicists have discovered that so-called 'frustrated magnets' can produce skyrmions, tiny magnetic vortices that may be used in memory storage. This discovery opens up a new class of ...
