Yes, it varies inversely, i.e. as temperature increases the barrier potential decreases. It decreases by 2mV for degree Celsius rise of temperature.

What happens to the barrier potential when the temperature increases?
barrier potential P0=(kT/q)*ln(Na*Nd/Ni^2) when T ↑, P0↑.
Energy absorption is directly dependent on?
potential energy
Electricity is dependent upon what?
The magnitude of the electric potential is dependent upon the particle's charge and the electric field strength.
What is the typical value of the barrier potential for a germanium diode?
0.3v as opposed to the silicon 0.6v
What is the type of potential energy dependent upon an object's weight and distance from earths surface?
That is called gravitational potential energy.
What happens to the barrier potential when the temperature increases?

What happen to barrier potential when temperature increases?

What would cause the barrier potential to decrease from 0.7 V to 0.6 V?
The barrier potential may depend on the exact material; but you can't normally change that. It may also depend on temperature.Also, such a barrier potential is not fixed at some value (like 0.7 V); however, it's often close enough that you can consider it to be constant. But actually, the barrier potential depends on the current. At higher currents, the potential is slightly higher.
Why potential across pn junction is called potential barrier?
The potential across a pn junction is called potential barrier because majority charge carriers have to overcome this potential before crossing the junction.
Which is greater the breakdown voltage or the barrier potential?
Breakdown voltage is far greater than barrier potential. silicon:- break-down voltage :- 5v - 450 v barrier potential ;- 0.5v to 0.7 V
Joule Thomson effect is temperature dependent or not?
its temperature dependent
Why can't the potential barrier of a diode be used as a voltage source?
The potential barrier of a diode is caused by the movement of electrons to create holes. The electrons and holes create a potential barrier, but as this voltage will not supply current, it cannot be used as a voltage source.
Compare the characteristics of a silicon and germanium diode?
Potential barrier of silicon is 0.7, whereas potential barrier of germanium is 0.3
What is the potential barrier of germanium?
0.3 volt
What is electric potential dependent upon?
The magnitude of the electric potential is dependent upon the particle's charge and the electric field strength.
What are forward and reverse bias?
Forward bias is when the height of the depletion layer is reduced such that a greater number of majority charge carriers have sufficient energy to overcome the potential barrier while revers bias is when the height of the potential barrier is increased so that very few majority charge carriers have sufficient energy to surmount the potential barrier. All the above phenomena takes place when a potential barrier is applied across the pn junction.
What is the dependent variable in a temperature test?
volume or temperature
