Current Density in Semiconductor

Current Density in Semiconductor

### Formula

$$J=nev_d$$

### For Electrons and Holes

$$J=e(n\mu_n+p\mu_p)E$$

### Terminologies

- J → Current density.

- e → Charge of electron.

- n → Electron concentration.

- p → Hole concentration.

- μn, μp → Electron and hole mobility.

### Usage

- Used to calculate semiconductor current.
