(ii)
State the effect of increasing the temperature of the diode on the reverse saturation current.

Answer (i)
AIWritten by AI (gemini) - it can contain mistakes.
The current flowing through the diode during reverse bias is extremely small because it is entirely due to minority charge carriers, which are very few in number compared to majority carriers.
Answer (ii)

Extrinsic semiconductors are highly useful because their electrical conductivity can be precisely controlled and tuned by altering the concentration of dopant atoms (impurities). They form the basis of p-n junction diodes, transistors, and integrated circuits.
