A P-N junction (or N-P junction) is formed by creating two substrate materials of P type and N type on a semiconductor. P type means it is doped with free holes (electron depletion) and the N type is doped with electrons. Of course by physics, the free holes and free electrons would like to neutralize each other.
The element P belongs to Group 15 (Vb),  Nitrogen-Phosphorous-Arsenic group in the periodic table of  elements.   Phosphate is a weak, tri-basic anion  PO43- but that' â¦ s  not a 'chemical group'.
