| 中文摘要 | photocurrent (pc) spectra of zncdse-znse double multi-quantum wells are measured at different temperature. its corresponding photocurrent derivative (pcd) spectra are obtained by computing, and the pcd spectra have greatly enhanced the sensitivity of the relative weak pc signals. the polarization dependence of the pc spectra shows that the transitions observed in the pc spectra are heavy-hole related, and the transition energy coincide well with the results obtained by envelope function approximation including strain. the temperature dependence of the photocurrent curves indicates that the thermal activation is the dominant transport mechanism of the carriers in our samples. the concept of saturation temperature region is introduced to explain why the pc spectra have different temperature dependence in the samples with different structure parameters. it is found to be very useful in designing photovoltaic devices. |
