Morphology And Optical Properties Of Si(111)/Crsi2/Si And Si(111)/Mg2si/Si Systems With Self-Organized Quantum Dots
PHYSICS, CHEMISTRY AND APPLICATION OF NANOSTRUCTURES: REVIEWS AND SHORT NOTES TO NANOMEETING-2001(2001)
Abstract
Growth conditions of CrSi2 and Mg2Si quantum dots, their sizes and density on Si(111) substrates and optical properties of new materials were investigated. Technologies of CrSi2 and Mg2Si island formation on Si(111) were proposed, Two direct interband transitions at 0.95 eV and 1.30 eV were observed in CrSi2 quantum dot materials. It was shown that Mg2Si quantum dots do not influence strongly optical properties of silicon substrate.
