Fleeting electron-hole pairs are giving scientists a new window into optimizing light-emitting devices (LEDs). Using quantum ...

Electric field measurement has become a critical component in modern engineering and scientific applications. As power systems evolve towards smart grids and the energy internet, the need for ...

Imagine a satellite, floating in space. How would you measure its voltage? Yes, it probably has a non-zero voltage, a consequence of geospatial electric fields and ion and electron currents. The ...

a: Optically detected magnetic resonance (ODMR) spectra of the NV center for various bias voltages V. b: The local electric field; experimentally and theoretically obtained values are in good ...

As the Parker Solar Probe ventures closer to the sun, we are learning new things about our home star. In a new study, physicists led by the University of Iowa report the first definitive measurements ...

For the first time, scientists have measured a long-sought global electric field in the Earth’s atmosphere. This field, called the ambipolar electric field, was predicted to exist decades ago but ...

Scientists in the United States have discovered an electric field method to improve heat ...

New research from the Department of Energy's Oak Ridge National Laboratory, in collaboration with The Ohio State University and Amphenol Corporation, challenges conventional understanding about ...

When Scotty is beaming up, he’s working in the very far field. Distinguishing between near field and far field conditions is especially important in EMC testing. Published antenna factors and related ...

Researchers directly observed electron-hole pairs in light-emitting electrochemical cells, finding that ion-driven electric field changes affect recombination and that stable, lower-voltage fields ...
