Gaas reflectivity
Webdoped GaAs it was found that the Rm value could vary from <4% to as large as 14%. The Si doping level and the thermal history of the sample both influence the Rm value. The … WebIn particular the Differential Reflectivity spectra, that is the relative change of the overall reflectivity between the clean and the oxidized surface, is directly related to the dielectric function of the surface layer. Data for the GaAs (110) cleaved surface show electronic transitions at around 3.0 eV.
