PART A
The I-V curves analysis practice for LED is plotted in semi-log scale as shown below:
PART B
Question 1:
A bond-diagram that shows how Arsenic dopes Silicon n-type can be drawn below:
Arsenic is an n-type dopant. Its slower dispersion permits utilizing it for diffused intersections.
Arsenic is utilized for covered layers and it has a comparative nuclear sweep to silicon, high
fixations can be accomplished. Its diffusivity is about a tenth of phosphorus or boron, so is
utilized where the dopant should remain set up amid resulting warm preparing. Arsenic is
valuable for shallow disseminations where all around controlled unexpected limit is wanted. Its
favoured dopant is in VLSI circuits and in low resistivity ranges.
Question 2:
The carrier mobility decreases with temperature in Silicon because the versati...
