Temperature dependence of cavity-polariton energies in ZnO and CuCl microcavities

Abstract: Large vacuum Rabi splitting in ZnO-based hybrid microcavities observed at room temperature Appl. Phys. Lett. 94, 061103 (2009); 10.1063/1.3079398 Dielectric Si O 2 ∕ Zr O 2 distributed Bragg reflectors for ZnO microcavities prepared by the reactive heliconwave-excited-plasma sputtering methodWe have investigated the temperature dependence of the cavity-polariton energies in ZnO and CuCl microcavities with HfO 2 /SiO 2 distributed Bragg reflectors. From angle-resolved reflectance spectra at 10 K, we experimenta… Show more

“…It can be seen that the energy barrier decreases gradually in the order DE 1 > DE 2 > DE 3 , due to the increased Stokes shi. 28 This should result in a gradually decreasing probability of non-radiative transition from the excited state to the ground state following the sequence E o > E c > E a . Therefore, this causes the fastest drop in the emission intensity from E o excited state, next is from E c excited state and emission from E a excited state has slowest decay rate.…”

“…The microcavity can be synthesized from different semiconductor materials. To study the effect of the microcavity material we investigated the propagation of the long-lifetime polariton BEC in graphene in microcavities formed by semiconductor materials CuBr, ZnSe, CdTe, and ZnO [41] that is, by those materials, which were utilized for the experimental studies of microcavity polaritons [16,17,25,[42][43][44][45][46][47]. According to Eqs.…”

“…1) Their bosonic properties in Bose-Einstein condensation [2][3][4][5] and polariton lasing [6][7][8][9][10] have attracted much attention. Recently, a wide-gap semiconductor, ZnO, 7,[10][11][12][13][14][15][16] has been adopted as the active layer of microcavities because the excitons in ZnO have large oscillator strengths and binding energies, which lead to large Rabi splitting energies and high thermal stability, respectively. These characteristics are advantageous for applications of microcavities.…”
