if the donor consecration ( nd )is much larger than the intrinsic concentration( ni )then n0=nd when n0 is the thermal equilibrium concentration of free electron
so : nopo=ni2 (when p0 is the thermal equilibrium concentration of holes )
po=ni2/nd
do some basic math we got nd=ni2/po

What is meant by step graded junction?
A step graded junction is the pn junction in which impurity concentration does not change abruptly from donor to acceptor but varies smoothly
What is the difference between step graded and linearly graded semiconductor p-n junction?
In step-graded the acceptor and donor concentrations in the semiconductor are constants up to the junction.In a linearly-graded junction, impurity concentration varies linearly with distance from the junction
What is a compensated semiconductor?
compensated semiconductor...SEMICONDUCTORS WHICH CONTAIN BOTH DONOR AND ACCEPTOR DOPANT ATOMS IN SAME REGION IS CALLED COMPENSATED SEMICONDUCTOR.

What is the concentration factor formula used to calculate the concentration of a substance in a solution?
The concentration factor formula used to calculate the concentration of a substance in a solution is: Concentration (Amount of Substance / Volume of Solution) Dilution Factor
How do you calculate the concentration of a stock solution?
To calculate the concentration of a stock solution, divide the amount of solute by the volume of solvent, and then multiply by 100 to get the concentration in percent.
How can one use the dilution factor to calculate concentration effectively?
To calculate concentration effectively using the dilution factor, you can multiply the initial concentration by the dilution factor. This will give you the final concentration after dilution. The formula is: Final concentration Initial concentration x Dilution factor.
How to calculate concentration after dilution?
To calculate the concentration after dilution, use the formula: C1V1 C2V2. Where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume. Simply plug in the values and solve for the unknown concentration.
How can one calculate the original concentration from a given dilution factor?
To calculate the original concentration from a given dilution factor, you can use the formula: Original concentration Final concentration / Dilution factor. This formula helps determine the initial concentration of a solution before it was diluted.
How can one calculate the acid dissociation constant (Ka) from the concentration of a solution?
To calculate the acid dissociation constant (Ka) from the concentration of a solution, you can use the formula Ka HA- / HA, where H is the concentration of hydrogen ions, A- is the concentration of the conjugate base, and HA is the concentration of the acid.
How to calculate the concentration of sulfur trioxide by knowing the oleum concentration?
To calculate the concentration of sulfur trioxide in oleum, you can use the formula below: Concentration of SO3 = (Oleum concentration x 2) / (3.14) This formula assumes that the oleum concentration is given as a percentage by weight. Simply plug in the value of the oleum concentration into the formula to find the concentration of sulfur trioxide.
How do you calculate concentration when given density?
You cannot.
How do you calculate the concentration of a solution?
To calculate the concentration of a solution, you divide the amount of solute by the volume of the solution. This gives you the concentration in units such as moles per liter (M) or grams per liter (g/L).
How to calculate the concentration of a solution?
To calculate the concentration of a solution, divide the amount of solute by the volume of the solution. This will give you the concentration in units such as moles per liter (M) or grams per liter (g/L).
How to calculate concentration from molarity?
To calculate concentration from molarity, you can use the formula: concentration (in g/L) molarity (in mol/L) x molar mass (in g/mol). This formula helps you convert the molarity of a solution into its concentration in grams per liter.
How to calculate protein concentration from absorbance at 280 nm?
To calculate protein concentration from absorbance at 280 nm, you can use the Beer-Lambert Law. This law states that absorbance is directly proportional to concentration and path length. By measuring the absorbance of the protein sample at 280 nm and using the extinction coefficient of the protein, you can calculate the concentration of the protein in the sample.
