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 ...

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 ...

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 ...

X-ray spectroscopic techniques rely on the element-specificity of inner-shell photoexcitation/ionization to probe electronic densities with atomic-site precision. The ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...
