“…This leads to the decrease of scattering efficiency and, therefore to the decrease of ELR with increasing wire radius. Similar behavior is obtained for hot-electron-energy relaxation caused by electron-POphonon scattering in 1D [11] and 2D [24] systems. Figure 2 shows also the dominant character of 5 n = modes over the 3 n = and 4 n = ones.…”

The hot‐electron energy‐loss rate conditioned by acoustic (LA) phonon modes for a free‐standing InGaAs cylindrical quantum wire is investigated theoretically. The energy‐loss rate as a function of wire radius, electron density and electron temperature is obtained. The comparison of our theoretical results for energy‐loss rate per electron with the experimental results obtained in the acoustic‐phonon scattering regime shows a sufficient agreement.

“…Thus the phonon distribution is perturbed, and nonequilibrium or hot phonons are produced if the phonon lifetime is not too small. The hot phonons have been found to play an important role in slowing down the cooling rate of 2D hot electrons [18,19]. We calculate ELR using the electrontemperature model [20,21].…”

“…Several experimental and theoretical studies of hot charge carrier phenomena in TCQW structures have reported improved physical properties that enhanced performances. For instance, hot charge carrier phenomena were studied under high laser pumping intensity and electric field application to the lattice [4][5][6][7][8][9]. These reports of mid-IR and near-IR QW lasers used photoluminescence (PL) spectra to show that hot charge carrier phenomena can improve properties such as interband threshold energy.…”

In this research, we experimentally investigated the photoluminescence (PL) spectra of an undoped GaAs/Al0.36Ga0.64As Tunnel-Coupled Quantum Well (TCQW) at 300 K and 77 K. At 300 K, PL spectra were broadened at various laser intensities due to the characteristic quantum-confinement electron levels in the active region of the TCQW during pumping excitation. At 77 K, at selected excitation intensities, the high-energy tails in the PL spectra of the studied structure corresponded with hot electron temperatures as functions of the energy of emitted photons. The average scattering energy rate of hot electrons in the system was also studied at a lattice temperature of 77 K. The average scattering energy rate of hot electrons obtained from this experimental study was in agreement with the calculated theoretical value.
