In semiconductor physics, the flat band potential is a critical parameter that influences the properties and behavior of semiconductors in contact with other materials, such as electrolytes or p-n ...

Semiconductors rely on quantum effects such as band gaps, so we do have to discuss a bit of quantum stuff—we'll stick to plain language as much as possible. First, a bit of background.

Techniques for Band Gap Engineering vary, including doping, the introduction of impurities into a semiconductor to alter its electrical properties; strain engineering, where stress is applied to ...

"A flat band in a band structure is a very special type of frequency band where the group velocity remains zero across all wavenumbers," Bilal explains. "In practical terms, this means that sound ...

This can produce flat bands, which have been observed in 2D crystals previously. The team’s results are the first case of a 3D crystal with that property. The flat band term refers to the ...
