Many displays found in smartphones and televisions rely on thin-film transistors (TFTs) made from indium gallium zinc oxide ...

In a discovery that brings a legendary quantum theory to life, physicists at Princeton University have directly observed Hofstadter’s butterfly — a fractal pattern in electron energy levels ...

An attosecond—or 0.000000000000000001 second—is no time at all for a person. That is not so for electrons, atoms and ...

Enrique Rico Ortega and Sofia Vallecorsa explain how quantum computing will allow physicists to model complex dynamics, from ...

A new study published in Nature Physics introduces a theory of electron-phonon coupling that is affected by the quantum geometry of the electronic wavefunctions.

Quantum sensors have become important tools in low-energy particle physics. Michael Doser explores opportunities to exploit ...

While the original electron microscope arrived in the early 1930’s (there’s still a controversy to this day over who invented the very first one), scientists have relied on what are known as ...

Since it has 1 more electron than protons, chlorine has a charge of –1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full. For example, when ...

An electron from a new atom would have to join an atom in the H 2 molecule on the next energy level, further from the nucleus where it would not feel a strong enough attraction. An electron from an ...
