What is Thermal voltage?

In semiconductors, the Shockley diode equation—the relationship between the flow of electric current and the electrostatic potential across a p–n junction—depends on a characteristic voltage called the thermal voltage, denoted V_T. The thermal voltage depends on absolute temperature T as V_T = T / 11600 V
