Elements used

For some strange reason my computer is having difficulty uploading an image I was going to use to help explain where I am useing what materials. I will try again tomorrow at a different computer. If I succeed then I will have a visual to help explain it all. If not I will attempt to explain it with plain words. For now, Keryn, yes, I was using Gold. We switch to a platinum film because it is smoother, atomically speaking. We also needed another film that can stay metallic, conductive, even at temperatures of 1200 C. we are using Ta but soon I hope to use Molybdenum. Love you all.
