| Abstract: | Abstract: The photovoltage spectra of AlGaAs/GaAs multiple quantum wells at different vacuum have been measured and the vacuum sensitivity of photovoltage is re-ported. The experimental results show that the photovoltage decreases in a step - like manner at 105 Pa and increases in a sept - like manner at 0.1 Pa. It is believed that the variation of photovoltage with vacuum is due to the action of oxygen atoms adsorbing at the surface of AlGaAs/GaAs multiple quantum wells structure. |
