Hi, friends,

I need to prepare atomic-scaled smooth gold(111) film on a solid
substrates.  To date, I tried on slide glass with the Cr as adhesion
layer. As usually done int he literature, I also treat the sample with
flame annealing.  But the surface does not behave as expected.  The
problems are:

1) The gold surface is composed of particles (or grains) but not atomic
flat.

2) It seems that Cr atoms diffuse into gold bulk causing darker color,
which is consistent with the literal reports.

Does anyboday know how to prepare a nice gold film on Glass or Silicon
wafer (with or without native oxide) matching the following requires:

1) Good adhesion to withstand the neutral aqueous solution.

2) No Cr is used

3) The atomic flat Au(111) on the topmost layer can be easily obtained.

Thank you very much in advance for your help!
