Abstract

We have observed a negative persistent photoconductivity effect in In0.25Ga0.75Sb/InAs quantum wells with Shubnikov–de Haas measurements. The saturated reduction of the electron density in the InAs well was about 10%. The electron effective mass was found to be (0.048±0.004) m0 for an electron density of 18.0×1011 cm−2. The electron quantum lifetime decreased as the electron density was reduced by the negative persistent photoconductivity effect due to electron-hole interaction.
