The aim of this study is studying the influence of the donor concentration and temperature on the static
dielectric constant (&epsilonS) of heavily doped n-type InAs semiconductor. The variation of donor concentration caused an
exponential increase of &epsilonS at high values of donor density. Our calculations indicated that &epsilonS Our calculations indicated that &epsilonS has no meaning at
concentration above 3×1016 cm3. Above this value the static dielectric constant diverges so that the polarization
catastrophe occurred. The static dielectric constant dependence of resistivity shows that at high resistivity the static
dielectric constant appears to be nearly constant and equals the value &epsilonS = 14.5. This value is equal to the static
dielectric constant of InAs host semiconductor without doping. One can expect a divergence &epsilonS at very low
resistivity values at which polarization catastrophe can happen.
Key words: Heavily doped InAs, polarization catastrophe, static dielectric constant, , , ,
