摘要

1.method of determining the type of conductivity of degenerate semiconductor materials, mainly with different effective masses of electrons and holes, u043eu0441u043du043eu0432u0430u043du043du044b in the comparison of parameters measured in the study material and u044du0442u0430u043bu043eu043du0435 differs, however, in order to facilitate and ensure the touch determination of the type of p u0440u043eu0432u043eu0434u0438u043cu043eu0441u0442u0438 u043fu0440u0438u043fu043eu0432u0435u0440u0445u043du043eu0441u0442u043du044bu0445 layersthe benchmark used u043du0435u0432u044bu0440u043eu0436u0434u0435u043du043du044bu0439 semiconductor material, sample and standard light polarized light with a wavelength of not exceeding the length of the ox. the red border acquisitions u03bbu044du0442u0430u043bu043eu043du0430, and reinventing themselves and find the least u043eu0442u0441u0442u043eu044fu0449u0438u0435 wavelengths from each other and from the u03bbu0437u043du0430u0447u0435u043du0438u044f u03bbu0438 several wavelengths, which are the parameter values u044du043bu043bu0438u043fu0441u043eu043cu0435u0442u0440u0438u0447u0435u0441u043au043eu0433u043e psi model and standardin the range of wavelengths, and compares the parameters of several u03bbu0441u043du0438u043cu0430u044eu0442 dependence model u03c8u0438 standard u03c8u043eu0442 wavelength and determine the type of conductivity to the sign or u0394u03c8 (several) = psi, psi: u0394u03c8 (several) 0 - n - type u0394u03c8 (several) 0 - p - u0442u0438u043f.2. method for 1, which was the fact that the parameters u03c8u0438 u03c8u0438u0437u043cu0435u0440u044fu044eu0442 at a wavelength lying in the range of u03bbu2245 several u2245 several.
