Abstract
Carrier transport and recombination parameters in heavily doped silicon were examined. Data were presented for carrier diffusivity in both p- and n-type heavily doped silicon covering a broad range of doping concentrations from 10 to the 15th power to 10 to the 20th power atoms/cu cm. One of the highlights of the results showed that minority carrier diffusivities are higher by a factor of 2 in silicon compared to majority carrier diffusivities
