Ultra low density of CdTe quantum dots grown by MBE

This work presents methods of controlling the density of self-assembled CdTe quantum dots (QDs) grown by molecular beam epitaxy. Two approaches are discussed: increasing the deposition temperature of CdTe and the reduction of CdTe layer thickness. Photoluminescence (PL) measurements at low temperature confirms that both methods can be used for significant reduction of QDs density from 10$^{10}$QD/cm$^2$ to 10$^7$-10$^8$QD/cm$^2$. For very low QDs density, identification of all QDs lines observed in the spectrum is possible.

MBE grown microcavities based on selenium and tellurium compounds

In this work, we present three groups of microcavities: based on selenium compounds only, based on tellurium compounds only, and structures based on mixed selenium and tellurium compounds. We focus on their possible applications in the field of optoelectronic devices and fundamental physics (VCSELs, narrow range light sources, studies of cavity-polariton electrodynamics) in a range of wavelength from 540 to 760 nm.
