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.
The difference between n-type and p-type materials are impurities or dopants. Both n and p type are semiconductor materials that are 99.99+ % the same. n-type material has some of itâs constituent atoms replaced with other atoms that have an extra electron. p-type material atoms are replaced with other atoms that have a deficit of one electron.
