- Does Einstein relationship hold for activated diffusion?
- People argue that the forward dissociation and reverse passivation have similar activation barriers. Would you support the argument?
- What assumption did I make regarding diffusion of H in SiO2 that makes the derivation slightly imprecise? Hint. Crystal vs. amorphous structure.
- Can you explain physically why tunneling is less temperature sensitive than SiH bond dissociation?
- Would the “observed activation energy” decrease or increase if there are significant hole trapping?
- Where does the entropy hide in classical rate equations? How do we account for it when we discuss semiconductor physics?
