A `Si` and a `Ge` diode has identical physical dimensions. The band gap in `Si` is larger than that in `Ge`. An indentical reverse bias is applied across the diodes.

A

The reverse current in `Ge` is larger than that in `Si`

B

The reverse current in `Si` is larger than that in `Ge`

C

The reverse current is identical in the two diodes

D

The relative magnitude of the reverse currents cannot be determined from the given data only.
