The interface at which p-type silicon and n-type silicon make contact ... zone" that acts as a non-conductive barrier. The PN junction is one of the primary building blocks of semiconductors.

The chip starts out as a thin wafer of P-type silicon. This is then coated with a layer of silicon dioxide -- kind of a silicon rust, which doesn't conduct electricity. On top of this is placed a ...

Fabrication of resistors, capacitors, p-n junction and Schottky Barrier diodes, BJT's and MOS devices and Integrated circuits. Topics include: silicon structure, wafer preparation, sequential ...

In solar module recycling, the corrosive acid is used for separating silicon from the cell by removing the antireflecting coating, silver, lead, and p-n junction. The corrosive acid was replaced ...
