We define the recombination rate for electron–hole pairs at the interfaces as the charge carrier flux crossing from one layer to another. The recombination Results and discussion In this section, we calculate the recombination rates for n-type and p-type single quantum wells (SQWs) made from ...

Recombination lifetimeFar-infrared (FIR) photoconductivity induced by cyclotron resonance in edge states of quantum Hall devices are studied by carrying out time-resolved measurements. It is found that the recombination of electron–hole pairs excited via cyclotron resonance in edge states is ...

The exciting electron beam results in a high generation rate density of electron-hole pairs, which may drive the system into nonlinear regimes. An analytic model is presented which describes the EBIC response when the {\it total} electron-hole pair generation rate exceeds the rate at which ...
52. Those parameters affect mainly the electronic coupling in the electron–hole pairs, which establishes the rate of back-electron transfer (recombination) to the ground state. Thus, we hypothesize that two distinct pools of electron–hole pairs with different electronic couplings are generated ...
the plasmon would be excited near 670 nm. The plasmon resonance can be damped by the generation of hot electron–hole pairs via Landau damping, which is a pure quantum mechanical process48,52. In Landau damping, a plasmon quantum can be transferred into a single electron–hole pair excitati...
4-Stilbenecarboxaldehyde (4SCA) at pH 3 was added to TiO2 anatase to form a new catalyst where the aldehyde carbonyl group reacts with the TiO2-OH to form the corresponding acetal (4SCA-TiO2). 4SCA-TiO2 significantly retards the electron recombination wh
