An assistant professor teaching physics requested a quote for the following:
I need to have an Ra of 4-6 angstroms. We are coating with diamond like carbon and hitting it with a cold neutron beam to study the surface density of the material.
What do you think would work best for PLD (pulsed laser deposition) system, coating with DLC to have the smoothness of an Rms of about 4-6 Angstroms which will be needed for a smooth reflection for the cold neutron beam?

A space power researcher requested a quote for the following:
Do you carry any wafers with diamond like carbon films on them? Do you have any sapphire wafers with diamond like carbon films?
We would most likely need a few 2" or 3" wafers. I will have to let you know the film thickness, but it would probably need to be around 300 nm or if they come with a standard thickness. Do you know what the thickness would be?

A PhD candidate requested a quote for the following:
We are interested in silicon wafers covered with ~90nm of smooth diamond-like carbon (DLC). In case you could provide such material, could you send me information on the material as well as on the prices.
The quality and properties of the silicon itself do not matter too much, it just needs to be fairly conductive (again, the exact value doesn't really matter).
On the other hand, the quality of the DLC (especially the roughness) is very important. If it is possible, we would prefer to have no oxide between the Si and the DLC (or only a very thin one).
We would prefer wafers of 2-3 inch diameter.
Is this information sufficient? If the selection is still too big, we will be interested in the material with the lowest price (The above properties are more important, though)
