What methods can be used to measure the thickness of very thin metal films in the 10 to 50 Angstrom range?

The films can be deposited on a substrate that would enable a thickness measurement, e.g. glass, silicon, etc. I would also appreciate advice on depositing very thin metal films by thermal...

What is the atomic density of Indium Oxide?

Using a = 1.0117 nm for cubic In2O3 and 16 atoms per unit cell, I calculate 16 x (1,0117E-7 cm)-3 = 1.55E+22 atoms/cm3. If I am doping In2O3 at 2%, the concentration would be 0.02 x 1.55E+22 =...
