Donor Concentration Solution

STEP 0: Pre-Calculation Summary

Formula Used

Donor Concentration = Total Acceptor Charge/([Charge-e]*Charge Penetration P-type*Junction Area)
N_d = |Q|/([Charge-e]*x_po*A_j)
This formula uses 1 Constants, 4 Variables

Constants Used

[Charge-e] - Charge of electron Value Taken As 1.60217662E-19

Variables Used

Donor Concentration - (Measured in 1 per Cubic Meter) - Donor concentration refers to the concentration or density of donor atoms in a semiconductor material.
Total Acceptor Charge - (Measured in Coulomb) - Total Acceptor Charge refers to the overall net charge associated with the acceptor atoms in a semiconductor material or device.
Charge Penetration P-type - (Measured in Meter) - Charge Penetration P-type refers to the phenomenon where dopant atoms, such as boron or gallium, introduce holes into the crystal lattice of the semiconductor material, typically silicon or germanium.
Junction Area - (Measured in Square Meter) - The Junction Area is the boundary or interface area between two types of semiconductor materials in a pn diode.

STEP 1: Convert Input(s) to Base Unit

Total Acceptor Charge: 13 Coulomb --> 13 Coulomb No Conversion Required
Charge Penetration P-type: 0.06 Micrometer --> 6E-08 Meter (Check conversion here)
Junction Area: 5401.3 Square Micrometer --> 5.4013E-09 Square Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N_d = |Q|/([Charge-e]*x_po*A_j) --> 13/([Charge-e]*6E-08*5.4013E-09)

Evaluating ... ...

N_d = 2.50370647427462E+35

STEP 3: Convert Result to Output's Unit

2.50370647427462E+35 1 per Cubic Meter --> No Conversion Required

FINAL ANSWER

2.50370647427462E+35 ≈ 2.5E+35 1 per Cubic Meter <-- Donor Concentration

What is a Donor atom?

A donor is a dopant atom that, when added to a semiconductor, can form a n-type region. A donor atom has more electrons available for bonding with neighboring atoms than is required for an atom in the host semiconductor.

How to Calculate Donor Concentration?

Donor Concentration calculator uses Donor Concentration = Total Acceptor Charge/([Charge-e]*Charge Penetration P-type*Junction Area) to calculate the Donor Concentration, The Donor Concentration formula is defined as these concentrations can be changed by many orders of magnitude by doping, which means adding to a semiconductor impurity atoms that can “donate” electrons to the conduction band. Donor Concentration is denoted by N_d symbol.

How to calculate Donor Concentration using this online calculator? To use this online calculator for Donor Concentration, enter Total Acceptor Charge (|Q|), Charge Penetration P-type (x_po) & Junction Area (A_j) and hit the calculate button. Here is how the Donor Concentration calculation can be explained with given input values -> 2.5E+35 = 13/([Charge-e]*6E-08*5.4013E-09).

FAQ

What is Donor Concentration?

The Donor Concentration formula is defined as these concentrations can be changed by many orders of magnitude by doping, which means adding to a semiconductor impurity atoms that can “donate” electrons to the conduction band and is represented as N_d = |Q|/([Charge-e]*x_po*A_j) or Donor Concentration = Total Acceptor Charge/([Charge-e]*Charge Penetration P-type*Junction Area). Total Acceptor Charge refers to the overall net charge associated with the acceptor atoms in a semiconductor material or device, Charge Penetration P-type refers to the phenomenon where dopant atoms, such as boron or gallium, introduce holes into the crystal lattice of the semiconductor material, typically silicon or germanium & The Junction Area is the boundary or interface area between two types of semiconductor materials in a pn diode.

How to calculate Donor Concentration?

The Donor Concentration formula is defined as these concentrations can be changed by many orders of magnitude by doping, which means adding to a semiconductor impurity atoms that can “donate” electrons to the conduction band is calculated using Donor Concentration = Total Acceptor Charge/([Charge-e]*Charge Penetration P-type*Junction Area). To calculate Donor Concentration, you need Total Acceptor Charge (|Q|), Charge Penetration P-type (x_po) & Junction Area (A_j). With our tool, you need to enter the respective value for Total Acceptor Charge, Charge Penetration P-type & Junction Area and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
