As shown in figure 2, the Raman spectrum is different when it is recorded at an atomic step of the surface. Furthermore, the characteristic vibration modes can be observed selectively at the locally ...

Using this pioneering instrument, researchers have observed—for the first time—the interactions between electrons and an exotic atomic vibration ... the electronic spectrum of various materials.

Phonons are a product of atomic vibration, which is similar to breathing ... When the researchers measured the spectrum of the emitted light, they noticed several equally spaced peaks.

A type of atomic vibration never before seen in ordinary solid materials has been observed in uranium. Using X rays and neutrons to monitor crystals of the heavy metal while they’re being heated ...
