Opposite

In a forward-biased BJT, the bending of the energy diagram is (same, opposite) as the difference in the Fermi level present in the graph.

2
New cards

Base transport factor

Fraction of emitter majority carriers that reach the collector.

3
New cards

Emitter efficiency

Fraction of emitter current that is due to majority carriers (electrons for an NPN BJT).

4
New cards

Transistor a

Fraction of emitter current that becomes majority carrier collector current.

5

All

The (emitter current, collector current, base current, all, two, none) is proportional to e^(Vbe/Vt)-1.
