Background noise and measurements

Consider a homogeneous semiconductor bar of length L measured along the Ox axis, with two ohmic contacts (electrodes) at its ends, of type N ⁺ , such that the hole population can be neglected.

Let q denote the charge of the electron, n the electron density, $\overrightarrow{J_n}$ the current density vector, G _n and R _n the electron densities per unit volume and per second, which, respectively, arrive in...
