The time dependence of conductivity due to polarization of electron-holes pairs by the electric field of the THz pulse is found as a function of the sum of the electron-hole mobilities and delay time between the pump and probe pulses.
electron pairselectronsfree radicalsgamma radiationirradiationreaction kineticsspectraRECENT studies on γ-irradiated frozen aqueous solutions at 77° K have led to the elucidation of the kinetics of the reactions of electrons and holes produced by radiation 1 . From this it can be inferred that the ...
5c). Under light irradiation, hot electron–hole pairs are formed on irradiated Bi-Hx nanosheets through plasmonic excitation, as shown in Fig. 5a. The plasmonic hot holes are consumed by the H atoms stored in Bi-Hx/NF (H + h+ → H+). In one operation, reactive H+ and e...
Fig. 26 shows the four steps by which OSCs are believed to operate; the process ultimately leads to the photogeneration of excitons and collection of charges in a simple bilayer device architecture. In the first step, bound electron–hole pairs are generated within one of the organic layers ...
the injected electrons from the electron beam unbalance the equilibrium of the semiconductor and electron/ hole pairs are created. Within the depletion region, the natural field removes excess charge, creating increased reversed bias current. As a result, EBIC signals are generated primarily from burie...
The working principle is based on the generation of electron-hole pairs by the backscattered electrons which escape the sample and are absorbed by the detector. The amount of these pairs depends on the energy of the backscattered electrons. The p-n junction is connected to ...
The most common BSE detectors are solid state detectors which typically contain p-n junctions. The working principle is based on the generation of electron-hole pairs by the backscattered electrons which escape the sample and are absorbed by the detector. The amount of these ...

Density of electron-hole pairslaser diodecoherent feedbackThe average value in the time domain of the density of electron-hole pairs in a semiconductor laser with coherent feedback is calculated under conditions of minimal pump energy. This value is found to be finite; the significance of this ...
(Eh). Electron-hole pairs are generated from such collisions, with the total number being exponentially dependent on the reciprocal of the electric field, -1/Emax. The electrons produced in this manner are either attracted to the drain (adding to the drain current). The generated holes, enter...
