Physicists solve quantum tunneling mystery

An international team of scientists studying ultrafast physics have solved a mystery of quantum mechanics, and found that quantum tunneling is an instantaneous process.

Quantum effects in nanometer-scale metallic structures

Plasmonic devices combine the 'super speed' of optics with the 'super small' of microelectronics. These devices exhibit quantum effects and show promise as possible ultrafast circuit elements, but current material processing ...

Long-range tunneling of quantum particles

The quantum tunnel effect manifests itself in a multitude of well-known phenomena. Experimental physicists in Innsbruck, Austria, have now directly observed quantum particles transmitting through a whole series of up to five ...

Electronics advance moves closer to a world beyond silicon

(Phys.org) —Researchers in the College of Engineering at Oregon State University have made a significant advance in the function of metal-insulator-metal, or MIM diodes, a technology premised on the assumption that the ...

New insights into the polymer mystique for conducting charges

For most of us, a modern lifestyle without polymers is unthinkable… if only we knew what they were. The ordinary hardware-store terms we use for them include "plastics, polyethylene, epoxy resins, paints, adhesives, rubber"—without ...

Toward tinier transistors

(Phys.org) —The foundation of many, many modern electronic devices – including computers, smart phones, and televisions – is the silicon transistor. However, the shrinking of consumer electronics is driving researchers ...

The quantum secret to alcohol reactions in space

Chemists have discovered that an 'impossible' reaction at cold temperatures actually occurs with vigour, which could change our understanding of how alcohols are formed and destroyed in space.
