Abstract
We have studied the long-wavelength photoinduced charge polarization and electron storage produced by infrared intersubband absorption in highly asymmetrical graded quantum wells. At zero bias a large photovoltage is observed, while at high bias the charge transfer probability approaches unity.Keywords
