Depositing Cr/Au layer on an ITO or on an Au thin layer. Will this electrode conduct well??

I have a glass substrate which is partially covered with ITO, partially covered with Au thin layer and the rest is a bare glass. On top of all this I need to evaporate a second layer of Au. For...

How can I measure the DC dielectric constant of a conducting thin-film?

All methods I found measured the frequency dependent dielectric but I'm looking for the DC dielectric conatant. And also I can't make a parallel plate capacitor from the thin film since it is...

What should be continuous at the interface of two materials, electric potential chemical potential or electrochemical potential?

At the interface between: 1) conductor/conductor 2) conductor/semiconductor (or dielectric) 3) semiconductor/semiconductor (or dielectric/dielectric) What quantity should be continuous? Is it the...

Boundary conditions are defined by Maxwell's/Gauss equations, so why we use ohmic/schottky boundaries in metal/semiconductor interfaces instead?

Maxwell's/Gauss equations define the electric fields and current density at the interface of metal/dielectric. Since semiconductor is a dielectric material, I would expect that these boundaries...

What is the DC dielectric constant of ITO?

I've searched the web, but couldn't find any research that measured the electric properties of ITO besides its conductivity. I was surprised to find that there is very few information on the zero...

Is the current equals sigma multiplied by the spatial derivative of the electrochemical energy (or fermi energy)?

I saw in a paper that the current in a metal is sigma (conductivity=e*mu*n) multiplied by dk/dx where k is the electrochemical energy (or fermi energy). It seems to me that it is some kind of a...

Is there charges inside a metal when there is a current flow?

In electrostatics, inside a metal there are no charges (electric field equals zero, thus one can find the potential using Laplace equation (together with the proper boundary conditions). Is it...

Is there band bending in metal organic interface?

What are the main differences between metal-inorganic and metal-organic interfaces? Is there a band bending or migs (metal induced gap states) in the metal-organic interface? And how the...

How to measure the dielectric constant of silicone/GaAs or other semiconductors?

The values of the relative dielectric constants for silicon/GaAs and other semiconductors are well known (11.9/12.9/etc.). They are used in static calculations (such as deplition region, currents,...
