p-n junction

n
(Electronics) electronics a boundary between a p-type and n-type semiconductor that functions as a rectifier and is used in diodes and junction transistors

For preparing p-n junction p- and n-type sliced gels were superimposed and a small force was applied on the metal electrode softly to stick the gels together.
This phenomenon takes place when the LED chip is powered, forward bias takes place at the p-n junction of the LED chip.
The p-n junction is still the basic building block of many semiconductor devices.
In the gallium nitride LEDs, the researchers used the local piezoelectric potential to tune the charge transport at the p-n junction.
The key to producing high-quality LED die is the growth of the epitaxial layers and an active p-n junction on an optimum substrate.
The construction of schottky diode is very different from conventional p-n junction in that a metal semiconductor junction is created.
P-N junction diodes were fabricated on samples obtained from two different wafers; (1) a complete HBT structure with an n (Si emitter), p (Si/Ge base), and an n/n+ (Si collector/sub-collector) deposited epitaxially (MBE) on a high resistivity p-Si substrate, (2) an HBT structure where epitaxial growth was terminated after the p-type base (Si/Ge) layer deposition.
The process creates a boundary called a p-n junction inside the device.
For unconcentrated sunlight, we believe our innovative approach in this SBIR program has the potential to achieve conversion efficiencies exceeding 40% with a single p-n junction device, approximately 20% higher than the current efficiencies of today's best multi-junction solar cells.
To create a p-n junction diode, the researchers work with materials at 55,000 times atmospheric pressure and at temperatures close to 1,700|C.
The p-n junction diode forms the basis for nearly all electronics and therefore, its quality is often a good predictor of the performance of a semiconductor device.
