Ultrafast extreme ultraviolet (XUV) spectroscopy is a powerful technique for probing the dynamics of atoms and molecules with attosecond time resolution. However, conventional XUV absorption ...

Attosecond transient absorption spectroscopy (ATAS) is an advanced technique that enables the direct observation of electron dynamics on the attosecond (10⁻¹⁸ second) timescale. By utilising isolated ...

Charge-carrier traps play a central role in the excited-state dynamics of semiconductor nanocrystals, but their influence is often difficult to measure directly. In CdS and CdSe nanorods of nonuniform ...

The sample generates the capacitance transient, which is then measured by the instrument. A temperature sweep is applied while employing a lock-in technique. Subsequently, the instrument filters out ...

NIR femtosecond pulse (pump pulse) induces the electron oscillation, which is monitored by the extreme ultraviolet IAP (probe pulse) based on the transient absorption spectroscopy. Disclaimer: AAAS ...

A photosensitizer (PS) is a chemical species that initiates a reaction upon absorption of light. Although the chemical compositions and practical applications of PS' differ widely, they all follow the ...
