Hi, please anyone could give any comment?

Hi all, I am trying to laminate two ITO-coated PET thin films together with heating (I believe the temperature generated by my laminator is above 80 Celsius degree), but they did not stick together even a little bit. I have checked online for a few articles, laminating PET with heating (above...

But anyone can tell what exactly is the problem with the over heating near the connections?

Yes the sputtering process should produce a uniform aluminium layer (for my case, the thickness was around 150nm). I still believe this should be a straight forward entry-level experiment, but I have worked on this for a week, tried a lot of different ways, but none of them came out as I...

I tried silver paste today, similar results. I doubt that if this is the right way to heat up a conductive thin film, it is really frustrated. I mean it should be a straight forward experiment, right? Do you know any workable alternative to heat up the film electrically? Or maybe heating the HPC...

The black spots are formed because of that, I tape a aluminium foil as a shield for the center area when doing sputtering, and the edge of the foil did not perfectly taped.

Thanks so much! This is what I have done today: I sputtered aluminum onto the AZO glass, however...the results are similar, the heat was mainly happened near the contact points, and the voltage distribution is also similar as before... I will try liquid metal later, but why the situation did...

edited, pic can be seen now?

Hi! I tried to heat the AZO conductive glass with a current source = 0.5A. However, I found the voltage near the contact points was almost 3 times higher than that on the glass surface (please see the picture for details). It means the heating effect mainly happened near the contact points...

oh...yes thanks a lot

I found two "forms" of it: p=\frac{\hbar}{i}\frac{d}{dx} p=-i\hbar\frac{d}{dx} how could they be the same??

Dear Zz, Sorry I have thought for a long time how to make myself clear, but I failed obviously. I just want to keep my post short hence did not tell the background of why I asking this question, because I think you would not interested in. You have answered my original question in your first...

Dear Zz, So the "transition range" from 4.22k to 4.20k shown in this diagram is only due to the issues such as impurities or instrument? But I believe it still require "a tiny period of time" to complete forming cooper pairs, right? I am looking for some "proofs" for the exist of this "tiny...

In the above picture it is clear that the transition from normal to superconducting states is not infinitesimally sharp, it drops from around 4.22K ~ end at 4.20K. I have two questions for this: 1) I wondering, what can be seen if taking a snap shot in the middle, say @ 4.21K? Would I see...

P.W. Anderson in his essay "more is different" said that: "no stationary state of a system has an electric dipole moment". He used an example of NH3 to illustrate that. I then checked online and found that, Chemists said there is dipole moment in NH3 molecule, but (nuclear) physicists claim...
