| 中文摘要 | The temperature induced blue shift of the intersubband absorption peak in GaAs/Al0.3Ga0.7As multiple quantum wells has been observed and calculated as a function of well thickness (L-W). As the temperature is lowered from 290 to 10 K, the absorption peak shifts to the higher energy by 7.1 meV. Calculation shows that the change in the barrier height dominates the blue shift at small L-W while exchange interaction is important for large L-W. At 80 K, the photocurrent spectrum (PCS) at 0 V bias (V-b) is gradually reduced and cut off by the barrier. The bias induced forbidden transition from the ground state, E-1, to the second excited state, E-3, is observed in PCS. The broadening of full width at half maximum of PCS is related to the bias induced forbidden transition at small bias (0 |
