PNP Biploar Junction Transistor Energy Band Diagram

[asd1249jf]

Homework Statement

Consider a PNP Biploar Junction Transistor uniformly doped in each region. Sketch the energy ban ddiagram for the case when the transistor is biased in

a)In thermal equilibrium
b)biased in the active region
c)biased in the cutoff (depletion) region

Homework Equations

None, this is a problem asked to sketch (To an approximate scale) the energy band diagram.

The Attempt at a Solution

I've sketched the first two, but neither my book or the notes contained an example of a PNP Bipolar Junction Transistor's energy band diagram at a cutoff region. can anyone show me a site or include a diagram of this?

I registered here specifically because I wanted an answer to this and couldn't find it--until I stumbled on http://www.ece.umn.edu/academics/students/graduate/documents/prelims/Fall_2006/Fall%202006%20-%20Semiconductor%20Devices.pdf PDF. For anyone else who googles this question and comes across this answer--you're welcome.

Text description: it's a mirror image of the PNP active diagram. There's a small hill at first and then a steep drop until it levels off.
