I want to measure the sheet resistivity/surface resistivity of Multilayer Insulation (MLI)used for cryogenics. It is basically a aluminized mylar. The thickness of aluminium is nearly 50nm and substrate is 6 micron PET.
We are able to measure the surface resistivity of MLI used for cryogenics by Van der Pauw method as well as four-probe method. I am very thankful for your suggestion. With regards Uday
