Calculate the built-in voltage of a junction in which the p and n regions are doped equally with 5 ×10^16 atoms / cm^3. Assume ni=1.5 ×10^10 / cm^3. With the terminals left open, what is the width of the depletion region, and how far does it extend into the p and n regions? If the cross-sectional area of the junction is 20 μm^2, find the magnitude of the charge stored on either side of the junction. | Numerade

SOLVED: 15. The diagram below may be used to explain the basic features of a p-n junction in semiconductor materials. The left side, part A, represents a conceptual situation where the adjacent p-doped and n-doped layers in a semiconductor crystal are considered to be separate from each other; if they were physically separated. The right side, part B, represents the p-n junction after this artificial restriction has been lifted, i.e . part B represents the situation as it exists in a real p-n ju

Atiq Ur Rahman on Instagram: "Korean scientists have developed a heat-resistant material capable of withstanding temperatures up to 1,000 degrees Celsius (1800 F) and extreme ultraviolet exposure. The material is a lanthanum-doped barium stannate oxide, created using pulsed laser deposition. It retains its optical properties under conditions that would normally degrade traditional materials. Its resilience to high heat and UV radiation makes it an ideal candidate for a range of applications, fro

SOLVED: Conductivity of semiconductors: The electrical conductivity of a semiconductor is given by σ=e(n μe p μh). The crucial difference between a metal and a semiconductor is that the carrier conceritration for the former can increase very strongly as the temperature is raised whereas it is coristant for the latter. In a very simple picture, this leads to the conclusion that semiconductors become more conductive at higher temperature whereas metals become less conductive. The decrease in the c
