Current Density due to Holes Solution

Follow our step by step solution on how to calculate Current Density due to Holes?

FIRST Step Consider the formula

J p = [Charge-e] \cdot N p \cdot μ p \cdot E I

Next Step Substitute values of Variables

∴

J p = [Charge-e] \cdot 2E+161/m³ \cdot 150m²/V*s \cdot 3.428V/m

Next Step Substitute values of Constants

∴

J p = 1.6E-19C \cdot 2E+161/m³ \cdot 150m²/V*s \cdot 3.428V/m

Next Step Prepare to Evaluate

∴

J p = 1.6E-19 \cdot 2E+16 \cdot 150 \cdot 3.428

Next Step Evaluate

∴

J p = 1.647678436008A/m²

LAST Step Rounding Answer

∴

J p = 1.6477A/m²
