hercule

My Pt nanowire is 30 nm thick x 50 nm wide x 70 um long. That means the thickness has 80 molecules. There are many documents about semiconductor nanowire (in FET - field effect transistor ) but Pt is not a semiconductor. And I think that 80 molecules thick nanowire is not suitable for the theory of quantized (quantum) conductance, for instance the theory of Persson about the conductance change per adsorbate molecule : G: conductance d: thickness F: width of r(e) ( the density of states of the adsorbed molecules at the Fermi energy of the metal) What formula can I apply for my Pt nanowire?

Pt's Rho number is not my difficulty. Because Pt nano wire or thin film just has several molecules on their horizontal section, I think we have to apply modern physics here, not classical one. Is it right?

I need help about Pt thin film or nano wire electric resistance. Because the thickness is in nanometer (~30nm), I think the resistance formula (R = p*l/s) is unusable. Please help me. If any material about that is available, please share with me. Thanks alot
