Abstract
A graded-gap quantum well structure where the band gap of the well is inclined along the growth direction has been fabricated, and its quantum-confined Stark effect has been observed experimentally. It has been confirmed that, in comparison with the conventional square-shaped quantum well, the graded-gap quantum well exhibits larger and nearly linear energy shift of the fundamental exciton absorption edge with applied field.Keywords
