摘要：

A novel structure, in which the potential profile of the coupled quantum well system is slightly inclined, is proposed for lowering the electric field required to transform the coupled system to a set of uncoupled single quantum wells. Numerical calculations of absorption spectra of graded coupled quantum wells under an electric field and room-temperature photocurrent spectra of fabricated p-i-n diode samples confirm the above enhanced effect.
