ABSTRACT
In semiconductors both boles and electrons contribute to electrical conduction. With an applied electric field E, the expression for current density is J = ( n μ n + p μ p ) e E = σ E https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203743102/9cca8f32-4688-4a1e-80c2-a6c9068f5153/content/eq796.tif"/>
