“…At Cr thicknesses (0.02-0.08 nm) the formation of 3D CrSi 2 islands has been found [11]. This mechanism correlates with STM data [12] of Cr deposition on Si(111) at 450-500°C, when different 2D and 3D islands have been formed on silicon surface at Cr thicknesses 0.008-0.08 nm (coverages 0.1-1.0 Ml). At higher Cr thicknesses (0.08-0.125 nm or 1.0-1.56 Ml) the lateral overgrowth of 3D CrSi 2 islands without its corresponding height increasing [11] has been observed.…”

“…However, their optical properties still have not been studied. Formation of magic clusters (MC) in reactive systems [1] differs from those in non-reactive ones [2] ('adsorbate-silicon' system is named 'reactive', if reaction resulted in silicide(s) formation takes place in it). The resulting compounds can differ in optical and conducting properties.…”

Magic clusters are the smallest ordered quantum dots; hence, they represent promising materials for optoelectronics. However, their optical properties still have not been studied. Therefore, the purpose of this work is investigation of optical properties of magic clusters formed both in reactive (Cr/Si (111)) and non-reactive (In/Si(111)) systems. The 'adsorbate-silicon' system named 'reactive', if reactions resulting in silicide(s) formation take place in it. Using differential reflectance spectroscopy, optical functions of Indium and Chromium magic clusters were obtained. Having analyzed obtained spectra, we conclude that Cr magic clusters are CrSi islands and Si surface covered by In magic clusters is a semiconductor. A new method of obtaining saturation coverage of studied surface structures was proposed.

“…Among these silicides the CrSi 2 compound has been intensively studied because of its 0.35 eV band gap, which gives perspective for the applications in optoelectronic devices, such as silicon-based photodetector [1][2][3]. Although there is a considerable sets of research devoted to the study of the growth phenomena in the relatively thick Cr-silicide films (with thickness of dozens to thousands Å ) [4][5][6] and elucidation of their structural, electrical and optical properties [7][8][9], but the work on very thin films (deposited amount is in range of few monolayers) of Cr on Si substrate is very limited [10]. In recent years, tremendous interests have been generated in the fabrication of nanoscale wires and tubes [11].…”
