Abstract

Measurements on a single quantum well infrared detector with its peak responsivity at 5.3 μm show a large Stark shift under bias. The detector has one graded barrier to enhance the effect of an electric field on the subband spacing. Several times greater change in the intersubband transition energy with applied field is obtained this way compared to the square well. Calculations show an even larger Stark shift possible with a stepped well structure.
