1) Can rectification be obtained with an ohmic contact?

2) Can holes tunnel through barriers like electrons?

3) Which has an absorption edge like a semiconductor, a metal or a transparent conductor?

4) Is the high carrier concentration in transparent conductors due to their ideal band structure or to the presence of defects and dopants?

5) If two different materials but with the same work function are brought into contact, does band bending result?
