How is a semiconductor junction formed?
P-n junctions are formed by joining n-type and p-type semiconductor materials, as shown below. ... However, in a p-n junction, when the electrons and holes move to the other side of the junction, they leave behind exposed charges on dopant atom sites, which are fixed in the crystal lattice and are unable to move.
How to Calculate Cross-Sectional Area of Junction?
Cross-Sectional Area of Junction calculator uses Junction Area = Total Acceptor Charge/([Charge-e]*Charge Penetration N-type*Acceptor Concentration) to calculate the Junction Area, The Cross-Sectional Area of Junction formula is defined as the area of a two-dimensional shape that is obtained when a three-dimensional object - such as a cylinder - is sliced perpendicular to some specified axis at a point. Junction Area is denoted by Aj symbol.
How to calculate Cross-Sectional Area of Junction using this online calculator? To use this online calculator for Cross-Sectional Area of Junction, enter Total Acceptor Charge (|Q|), Charge Penetration N-type (xno) & Acceptor Concentration (Na) and hit the calculate button. Here is how the Cross-Sectional Area of Junction calculation can be explained with given input values -> 5.4E+15 = 13/([Charge-e]*1.9E-08*7.9E+35).
