What would cause the barrier potential to decrease from 0.7 V to 0.6 V?

The barrier potential may depend on the exact material; but you can't normally change that. It may also depend on temperature.Also, such a barrier potential is not fixed at some value (like 0.7 V); however, it's often close enough that you can consider it to be constant. But actually, the barrier potential depends on the current. At higher currents, the potential is slightly higher.

Temperature increase. As temp increase increases resistance in conductors, the case of semiconductors is the reverse. The barrier voltage of a semiconductor is actually the voltage drop that occurs during current passage, when a semiconductor component is in ON (conductive) mode, a function of resistance - remember Ohm’s law. This is the phenomenon that causes a semiconductor component to get burnt up- a positive feedback effect of fault.
