1. p-n junction

   A p–n junction is a boundary or interface between two types of semiconductor materials, p-type and n-type, inside a single crystal of semiconductor. The "p" (positive) side contains an excess of holes, while the "n" (negative) side contains an excess of electrons in the outer shells of the electrically neutral atoms there. This allows electrical current to pass through the junction only in one direction. The p-n junction is created by doping, for example by ion implantation, diffusion of dopants, or by epitaxy (growing a layer of crystal doped with one type of dopant on top of a layer of crystal doped with another type of dopant). If two separate pieces of material were used, this would introduce a grain boundary between the semiconductors that would severely inhibit its utility by scattering the electrons and holes.p–n junctions are elementary "building blocks" of semiconductor electronic devices such as diodes, transistors, solar cells, light-emitting diodes (LEDs), and integrated circuits; they are the active sites where the electronic action of the device takes place. For example, a common type of transistor, the bipolar junction transistor (BJT), consists of two p–n junctions in series, in the form n–p–n or p–n–p; while a diode can be made from a single p-n junction. A Schottky junction is a special case of a p–n junction, where metal serves the role of the n-type semiconductor.

1. p-n junction

   A p-n junction is a type of semiconductor-semiconductor junction that forms between a p-type semiconductor, which has an excess of holes (positively charged), and an n-type semiconductor, which has an excess of electrons (negatively charged). This junction allows current to pass in only one direction and is crucial in the functioning of devices such as diodes, transistors, and most semiconductor devices. When they are combined, an interesting property emerges wherein electrons from the n-type side diffuse to the p-type side and combine with the holes, creating a region known as the depletion layer where no charge carriers exist.

2. Public Safety commissioner:

   That’s why we built 285, y’ all, it’s the bypass. This morning, Atlanta’s MARTA transit system increased rail services to accommodate the expected increase in travelers. By mid-day MARTA CEO Keith Parker was reporting a 25 percent surge in ridership. With highway capacity already at a premium, the I-85 closure comes at a time of peak demand. This weekend, spring break gets underway for many area school students. And Friday evening, the Atlanta Braves will inaugurate their new stadium with a preseason game. During construction of the new stadium, critics questioned the impact the facility would have on traffic at its location near the junction of I-285 and I-75 in suburban Cobb County. Now that I-75 is the only northbound interstate out of downtown Atlanta, traffic plans will be put to the test. Despite the inconvenience, some residents and officials are putting Thursday’s disaster in perspective.
