There are many article showing VB in eV or specifying it as eV (V) For example: if the Vb value is 1.5 it is given as VB= 1.5 eV(or V) does this mean eV and V the same? or should we convert using any other formula?
Dear Kavya Kalidasan, do you have an example for the usage of "V" (volt) that you could refer to here? So far I've always seen "eV". Only this unit of measurement gives an energy.
The correct way to provide an energy is of course by using an energy unit, i.e. "eV" as already specified by Jan-Martin Wagner .
Sometimes, people omit the "e" out of laziness or because they have very old software that spits out measured voltages instead of an energy value, so in most such cases just recalculating from V to eV will do it.
If you have a specific reference in mind, you can post it here, so we can check it.
I agree with both previous colleagues. The hand waving explanation is that the "V" being electric potential per charge, but from photoelectric relation the equivalent energy of a scattered charge from the surface is then be qV (electric potential energy). The "Gaussian" unit for this energy is eV, and the IS unit is Joules.
