Question

When the reverse voltage across a Si p-n junction is increased in value by 0.8 V, the depletion layer widens by 0.6 micron

(0.00006 cm). Calculate the change in junction capacitance per unit area.

The relative permittivity of Si is 11.8

The permittivity of free space is 1.04 x 10^-12 F/cm

Select one:

O a. 23600 F/cm^2

O b. -2 uF/m^2

O c. -0.2 uF/cm^2

O d. 0.3 muF/cm^2
