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

The technique, called asynchronous and interferometric transient absorption spectroscopy (AI-TA), provides ultrafast measurements of excited-state dynamics and structural transformations in light ...

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 ...

Ultrafast transient absorption spectroscopy studies showed a surface state affecting photoinduced charge (electron/hole) transmission in GQD NH systems. The anticipated charge transfer times for ...

­The Deep Level Transient Spectroscopy system gauges capacitance and current transients through a lock-in integrator and cryostat within the DLS system. Measurement modes encompass: ...

The emission at about 420 nm resulted from the recombination of electrons with neutral copper vacancies, according to steady-state photoluminescence (PL) spectra. Using femtosecond transient ...
