Paper Abstract

A number of delta-doped by Sn for a wide range of Sn doping densities structures on vicinal GaAs (001) substrates with a misorientation angle of 3 degree(s) have been prepared using molecular beam epitaxy growth technique. Because of the relatively high segregation ability, Sn, when deposited on the terraces, may accumulate at the step edges and form quasi-one dimensional channels. Magnetotransport, the Shubnikov de Haas (SdH) and the Hall effects, photoluminescence and photoconductivity have been investigated in the temperature range 0.4-300 K. The Hall resisitivity, SdH effect and the magnetoresistance were measured in magnetic fields up to 40 T directed perpendicular or parallel to the plane of the delta-layer. The photoconductivity has been investigated for wavelengths (lambda) equals650-1200nm in the temperature interval Tequals4.2-300 K.
