Net Distribution Formula:
| From: | To: |
Net Distribution is spatial or numerical representation of the net quantity or concentration of a specific entity or property. In semiconductor physics, it represents the difference between donor and acceptor concentrations divided by the graded constant.
The calculator uses the Net Distribution formula:
Where:
Explanation: The formula calculates the net impurity distribution by taking the difference between donor and acceptor concentrations and dividing by the graded constant, which gives the slope of net impurity distribution.
Details: Accurate net distribution calculation is crucial for semiconductor device modeling, understanding doping profiles, and analyzing charge distribution in semiconductor materials.
Tips: Enter donor concentration and acceptor concentration in 1/m³, and graded constant. All values must be valid (graded constant cannot be zero).
Q1: What is donor concentration?
A: Donor concentration refers to the concentration or density of donor atoms in a semiconductor material.
Q2: What is acceptor concentration?
A: Acceptor concentration is the concentration of an acceptor or dopant atom that when substituted into a semiconductor lattice forms a p-type region.
Q3: What does graded constant represent?
A: Graded constant gives the slope of net impurity distribution. It is the rate between different doping concentrations in a graded region near a junction.
Q4: What are typical units for these measurements?
A: Concentrations are typically measured in 1/m³ (atoms per cubic meter), while graded constant is dimensionless.
Q5: When is this calculation most useful?
A: This calculation is particularly useful in semiconductor device fabrication and analysis, especially when working with graded junctions and impurity distributions.
