An Osaka Metropolitan University-led research team investigated the decay time of coherent longitudinal optical (LO) phonons both in a GaAs1−xNx epilayer and in a GaAs single crystal to clarify the ...

Free-electron laser (FEL) sources can generate tunable short-wavelength coherent pulses that can be used for studying structure and dynamics of matter in different forms. In this open collection, we ...

When an electron travels through a polar crystalline solid, its negative charge attracts the positively charged atomic cores, causing the surrounding crystal lattice to deform. The electron and ...

Electron Energy Loss Spectroscopy (EELS) measures how much energy electrons lose while interacting with a sample. These findings are then utilized to characterize a broad range of materials. A diagram ...

X-ray photoelectron spectroscopy is based on the same principle as all photoelectron spectroscopy methods. If a molecule or material is irradiated with light of a known energy above the ionization ...

For the first time, researchers have shown that self-assembled phosphorus chains can host genuinely one-dimensional electron ...

Leveraging its expertise in fields such as integrated circuits for telecommunications, France-based research institute CEA-Leti says it is “driving innovation in cutting-edge applications”. One of its ...

Scientists can now see a hidden battery ingredient — and it could supercharge how fast and how long lithium-ion batteries ...

Antibodies are a major component of adaptive immunity against invading pathogens. In this presentation, we will describe an analytical approach to characterize the antigen-specific antibody repertoire ...

While many people often use spectroscopy and spectrometry interchangeably, there are some subtle differences in their exact meanings and the associated experimental techniques they are used to ...
