Sb deposition by either thermal or sputtering seems to be an extremely dangerous thing to do. I would exercise caution and talk to safety for precautions. A face mask I think would be a good thing when you are cleaning the equipment afterwards. That is take the temperature of the deposition and divide it by melting point of antimony is about 0.3 so I don't think that is a problem. However, antimony has an appreciable vapor pressure at lower temperatures, so your Sb isn't impinging on a substrate and laying there. If it is revaporizing you might have all sorts of texturing phenomenon.

Could someone please share their experience about the optimum parameters to get a fair deposition? Also is sputtering Sb a beter option than depositing it with the thermal evaporator? Thanks.
