Zener diodes have higher dopant densities as compared to ordinary p-n junction diodes. How does it affect the width of the depletion layer and the junction field?

The width of the depletion region depends on the dopant density. i.e higher the dopant density of charge carriers the lower the width of depletion region. so in Zener diode, higher concentration of dopant charges, the depletion region decreases. therefore the junction field increases.
