Changes in electron density of InAs/AlGaSb single quantum wells were investigated at 1.4 K under visible and infrared LED illumination via the persistent photoconductivity effect.The electron density decreased to 1.1x10¹⁵ m^-2 after visible-light illumination and increased to 7.4x10¹⁵ m^-2 after infrared-light illumination. Reversible control of the electron density over a wide range was achieved by alternating visible and infrared illumination.
