Infrared absorption of holes in a parabolic quantum well M. Sundaram
... We observe the infrared absorption of holes in a wide graded Alx Ga12x As parabolic quantum well to be at a single frequency, independent of the number of holes in the well. The resonant absorption frequency appears to be determined by the light hole mass, not the heavy hole mass. The generalized Ko ...
