General Questions and Answers / Re: voltage drop behavior

« on: May 15, 2018, 12:58 »

Dear Petr,

Thank you for your answer. let me ask my question in other words. If the voltage drops linearly (nonlinearly), may I conclude that the system is a semiconductor (metal)?

I calculated the voltage drop of two 2D systems in the same bias voltage; the voltage drop of the system which shows higher conductivity (current) drops linearly but the voltage drop of another system with a very weak current intensity has a concave shape.

Thanks in advance.

General Questions and Answers / voltage drop behavior

« on: May 15, 2018, 08:16 »

Dear experts,

In many systems, the voltage drop across to the transport direction is not a linear ramp, and it has convex or concave shapes. My question is that what is the meaning of this behavior?

What is the main difference between two systems where the voltage of one of them drops linearly across the central scattering region, but the other one does not drop linearly?

Thank you very much in advance.
