Popis: The effect of B dopants on the properties of InAs quantum dots is studied experimentally. It is shown that the incorporation of B atoms decreases the integral amount of InAs that is needed to form islands according to the Stransky-Krastanov mechanism and leads to an increase in the density of dots. At the same time, it is discovered that the sensitivity of InAs quantum dots to annealing increases, which leads to the degradation of the optical properties of these quantum dots during growth of covering layers.
