Abstract:
A method, which makes it possible to obtain semiconductor particles $V\approx$ 10$^{-20}$ cm$^3$ in volume (quantum dots) with a concentration of up to 10$^{11}$ cm$^{-2}$ and electrical contacts to each of them, is suggested. High variability in the electrical properties of such particles from a metal oxide (CuO or NiO) after the chemisorption of gas molecules is found.
