Main Question or Discussion Point

Will a current through the ptype + metal material be very low because of the ptype material?
Does a junction like a pn junction form between the ptype semiconductor and the metal?

Thanks for your time.

The electric properties of a metal can be viewed as a highly degenerated N-type semiconductor.
Therefore, P-metal can be treated as a pn diode. And it properties depends, as what yasir.ustb stated, on the work function of each materials.
