Decoration (noun). specifically, any mark of honor to be worn upon the person, as a medal, cross, or ribbon of an order of knighthood, bestowed for services in war, great achievements in literature, art, etc. Origin: [LL. decoratio: cf.
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.
Key Difference: The P Type and N Type are two different types of semiconductors. The P Type carries a positive charge, while the N type carries a negative charge. The charges depend on the hole concentration and the electron concentration. The P type semiconductor has a larger hole concentration, which results in the positive charge.
