The current-voltage characteristics is of prime concern in the study of semiconductor devices with light entering as a third variable in optoelectronics devices.The external characteristics of the device is determined by the interplay of the following internal variables:
1. Electron and hole currents
2. Potential
3. Electron and hole density
4. Doping
5. Temperature

Current: (EC6202 Electronic Devices and Circuits Notes)

There are two components of current; electron current density and hole current density. There are several mechanisms of current flow:
(i) Drift
(ii) Diffusion
(iii) thermionic emission
(iv) tunneling

The last two mechanisms are important often only at the interface of two different materials such as a metal-semiconductor junction or a semiconductor-semiconductor junction where the two semiconductors are of different materials. Tunneling is also important in the case of PN junctions where both sides are heavily doped.
