Junction Transition Width Solution

Follow our step by step solution on how to calculate Junction Transition Width?

FIRST Step Consider the formula

W j = x no \cdot (\frac{N a + N d}{N a})

Next Step Substitute values of Variables

∴

W j = 0.019μm \cdot (\frac{7.9E+351/m³ + 2.5E+351/m³}{7.9E+351/m³})

Next Step Convert Units

∴

W j = 1.9E-8m \cdot (\frac{7.9E+351/m³ + 2.5E+351/m³}{7.9E+351/m³})

Next Step Prepare to Evaluate

∴

W j = 1.9E-8 \cdot (\frac{7.9E+35 + 2.5E+35}{7.9E+35})

Next Step Evaluate

∴

W j = 2.50126582278481E-08m

Next Step Convert to Output's Unit

∴

W j = 0.0250126582278481μm

LAST Step Rounding Answer

∴

W j = 0.025μm
