I need a calibration (gauge) plate in order to check a scanning tunneling microscope. For that means I would need two atoms isolated from other atoms in an area of 50 nm (or more) radius on a glass plate? These two atoms must be at a distance of 10-30 nm. I will then look to resolve them.
My questions are:
1. Do they sell such plates?
2, If not how to build one?
I have an idea to dissolve a small amount of say Cu and then dilute to reach 1 atom in 1 ml. Then pour it on a glass plate and dry. Would this give me the gauge needed?
Hi,
First of all you can not take a STM measurements on a glass plate as it is a non-conductive material. Then why you complicate your life? In my opinion you should try standard samples, which are useful for testing STM machine like: Si(111), HOPG, Au etc.
