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.
What is PPS? Polyphenylene Sulfide (PPS) Polymer Characteristics. PPS is an engineering polymer whose structure is composed of benzene and sulfur. Polyphenylene sulfide (PPS) is a partially crystalline, high temperature performance polymer that has the chemical structure shown in the figure on the right. This polymer has a high melting point of approximately 280Â°C, excellent chemical resistance and is inherently flame retardant.
