Why the IV curve of msm photodetector is non-origin symmetric at my device ?

(Revised 2018.08~) Thanks for everyone wrote answers. The answer could be anythings. There are non-symmetric issues of main material, electorde, contact tip and more complex things mixed.

Electron affinity is the difference between the energy level of conduction band to vacuum level. That means how much energy is needed to pump out a electron from conduction band to vacuum level.

Work-function is the difference between fermi level and vacuum level.

You can follow the following book for more details.
