Researchers at the Paul Scherrer Institute PSI have succeeded for the first time in looking inside materials using the method of transient grating spectroscopy with ultrafast X-rays at SwissFEL. The ...
The organic solar cell (OSC) heterojunction interface is where key photophysical processes such as charge separation and recombination occur. The molecular orientation at the interface is one of the ...
Deep Level Transient Spectroscopy (DLTS) is considered to be a great tool for characterizing electrically active majority carrier traps in semiconductors [1]. The fundamental principle of DLTS ...
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 ...
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 ...
Absorption spectroscopy is one of the many techniques that utilize spectroscopic principles to study components of a mixture of substances. These are used to measure the absorption of radiation ...
Over the last several decades, ultrafast spectroscopic techniques have played a key and growing role in scientific discoveries in physics, materials science, biology, and chemistry while also proving ...
