Dear all

Pls contact me if you can provide some help for the calculation on the M-S-M model.
Using equation:

After plotting LnI vs.V,
I use the slope to get Eo, where Eo is in the unit of mV.
While if I continue with the calculation. using equations:

to calculate the carrier density n.

How do I transfer the unit of Eo(mV) to Eoo(eV)?

I would really appreciate any comments:)

Thank you for reaching out for help with your calculations on the M-S-M model. I am a scientist who specializes in this area and I would be happy to provide some assistance.

To transfer the unit of Eo (mV) to Eoo (eV), you can use the following conversion:

1 mV = 10^-3 V
1 eV = 1.6 x 10^-19 J

Therefore, to convert Eo from mV to eV, you can use the formula:

Eoo (eV) = Eo (mV) x 10^-3 V x 1.6 x 10^-19 J/eV

I hope this helps with your calculations. If you have any further questions, please feel free to reach out.


 

1. What is a metal-semiconductor-metal calculation?

A metal-semiconductor-metal calculation is a computational method used to analyze the electronic properties of a metal-semiconductor-metal (MSM) structure.
