6 FAQs about [Energy storage field recombination rate]

How do recombination rates affect the concentration of defects?

The concentration of generated defects typically increases with the dose of incoming particles, and decreases for increasing temperature and defect recombination rates. A variety of defect types and concentrations can be generated through these bombardment methods, with greatly varying energy cost among different techniques.

What happens when recombination and generation occur at equal rates?

The product of the electron and hole densities ( and ) is a constant at equilibrium, maintained by recombination and generation occurring at equal rates. When there is a surplus of carriers (i.e., ), the rate of recombination becomes greater than the rate of generation, driving the system back towards equilibrium.

What is the difference between defect generation and recombination?

Defect generation stores an amount of energy per defect equal to the formation energy E F . While defect recombination releases this energy in the form of heat, it requires activation over the energy barrier E A between the defect and transition state in the recombination reaction (Fig. 4 ).

What is the total stimulated recombination rate?

The total stimulated recombination rate is a summation of the lateral stimulated recombination rate in each QW that are shown in Fig. 3 c 1 to 3c 5. Device B has a higher stimulated recombination rate in all five quantum wells.

How to determine dominant carrier recombination mechanism of PSCs?

How do surface fields affect recombination?

Surface fields not only repel carriers from defective regions at the surface but also cause spatial separation of electrons and holes which has previously been shown to lead to depressed radiative recombination rates (that is, lower PLQE) and slowed recombination in materials such as InP 41, 44.
