Book excerpt: Radiotracer Zn65 was vapor diffused in GaAs and GaP single crystals in closed, evacuated quartz ampoules. The solubilities and diffusion profiles were obtained over the temperature range 700 to 1100 C. The solubility data were analyzed by assuming Zn-GaAs and Zn-GaP to be binary systems and considering the transfer of neutral Zn from the liquid to the solid where some Zn atoms become ionized acceptors. The solubilities and distribution coefficients of Zn in these two semiconductor were calculated as functions of temperature up to the melting point of the solvents. The experimentally measured diffusion profile exhibit a steep front for Zn in GaAs above 700 C and for Zn in GaP above 900 C. Application of the Boltzmann-Matano method to these profiles shows that the diffusion coefficient is strongly concentration-dependent. A precise evaluation of this dependence was obtained from isoconcentration diffusions performed at a fixed temperature: 900 C for Zn in GaAs and 1000 C for Zn in GaP. (Author).

Stanford Electronics Laboratories and published by . This book was released on 1964 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study undertakes: first, to establish the relationship of these anomalous profiles to the diffusion equation; second, to calculate the relationship among the parameters of the zinc-diffused layers; and third, to measure the resistivity of GaAs as a function of zinc concentration. The results of this study provide: first, a procedure for calculating concentration profiles for various surface concentrations for a system such as zinc in GaAs when only two experimentally measured profiles are known; second, design data concerning the electrical properties of the zinc-diffused layers; and third, measurements of resistivity as a function of zinc concentration in heavily doped GaAs.
