Reverse leakage current in a semiconductor
device is the current
from that semiconductor device when the device is reverse bias

When a semiconductor
device is reverse bias
ed it should not conduct any current
at all, even though, as a temperature effect, it will form electron-hole pairs (see Carrier generation and recombination
) at both sides of the union and therefore a very small current, which is named Reverse leakage current, this current will duplicate for each increment of 10°C in temperature.
The term it particularly applicable to is mostly semiconductor junctions diode

Semiconductor
A semiconductor is a material with electrical conductivity due to electron flow intermediate in magnitude between that of a conductor and an insulator. This means a conductivity roughly in the range of 103 to 10−8 siemens per centimeter...

Electric current
Electric current is a flow of electric charge through a medium.This charge is typically carried by moving electrons in a conductor such as wire...

P-n junction
A p–n junction is formed at the boundary between a P-type and N-type semiconductor created in a single crystal of semiconductor by doping, for example by ion implantation, diffusion of dopants, or by epitaxy .If two separate pieces of material were used, this would...

Carrier generation and recombination
In the solid state physics of semiconductors, carrier generation and recombination are processes by which mobile charge carriers are created and eliminated. Carrier generation and recombination processes are fundamental to the operation of many optoelectronic semiconductor devices, such as...

Diode
In electronics, a diode is a type of two-terminal electronic component with a nonlinear current–voltage characteristic. A semiconductor diode, the most common type today, is a crystalline piece of semiconductor material connected to two electrical terminals...
