What happens when you connect a ptype semiconductor to a metal conductor?

Click For Summary
Connecting a p-type semiconductor to a metal conductor can result in low current flow due to the properties of the p-type material. A junction similar to a pn junction may form between the p-type semiconductor and the metal, influenced by the work function of both materials. The electric properties of the metal can be compared to a highly degenerated n-type semiconductor, suggesting that the interaction behaves like a pn diode. The current characteristics and junction behavior depend significantly on the vacuum level and work function values. Understanding these factors is crucial for predicting the electrical behavior of the p-type and metal interface.

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.
 
A relative asked me about the following article: Experimental observation of a time rondeau crystal https://www.nature.com/articles/s41567-025-03028-y I pointed my relative to following article: Scientists Discovered a Time Crystal That Reveals a New Way to Order Time https://www.yahoo.com/news/articles/scientists-discovered-time-crystal-reveals-180055389.html This area is outside of my regular experience. I'm interested in radiation effects in polycrystalline material, i.e., grain...
