The energy-loss rate via polar-optical phonon scattering in quantum wires

Hot‐electron energy‐loss rate via LA‐phonon scattering in InGaAs quantum wire

“…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.…”

Hot-electron energy-loss rate via PO-phonon scattering in CdZnSe/ZnSe quantum wire

“…for cylindrical quantum well wire within the frame of the infinitely deep quantum well approximation [4].…”

“…Recently there has been considerable experimental [1][2][3] and theoretical ( [4] and references therein) interest in the hot-electron energy relaxation problem in polar semiconductors, particularly in one-dimensional GaAs structures. In the investigation of energy-loss processes in semiconductor quantum well wires (QWRs) we should deal with both electron and polar optical (PO) phonon confinement effects.…”

“…In Ref. [4] the PO phonon-caused electron ELR in QWRs embedded in polar material has been studied, taking into account phonon confinement effect, electron intersubband transition and hot-phonon bottleneck effect simultaneously. The electron-PO phonon interaction in a wire with circular cross-section is studied within the frame of dielectriccontinuum model.…”

“…[4] to study the hot-electron ELR in Cd 0.35 Zn 0.65 Se/ ZnSe QWR. We present a comparative analysis of the confined and interface phonons as well as intrasubband and intersubband transition contributions to electron ELR, taking into account the hot-phonon effect.…”
