Abstract
The effect of cadmium-selenide quantum dots addition on the electrical and photoelectric properties of nanocrystalline indium oxide with nanocrystal dimensions in the range from 7 to 40 nm is studied. By impedance spectroscopy, it is shown that the addition of quantum dots substantially influences the resistance of interfaces between In2O3 crystals. A change in the character of the photoconductivity spectrum of In2O3 upon the addition of CdSe quantum dots is detected, and it is established that this change depends on the In2O3-nanocrystal dimensions. An energy band diagram is proposed to explain the observed change in the photoconductivity spectrum of In2O3 upon the addition of CdSe quantum dots.
