We intend to study the magneto-transport properties of two dimensional electron-hole systems in the condition of ultra-low temperature and high magnetic field by SdH measurement and QHE measurement. In these samples, the SdH oscillations show a 2DEG behavior. We observed that the sample shows negative persistent photoconductivity effect at low temperature and high field under illumination. We want to compare with results before 4 years, so we change more sets of measurement. And we want to know if these samples still show the same effect after 4 years.
