I’m performing an experiment on fabricating compound thin films by Thermal Evaporation method.

But there is a difficulty, the material species couldn’t deposit on the substrate, I speculate the main cause is improper temperature gradient between the substrate and my graphite boat (please refer to the Figures below), I mean, the substrate’s temperature is too high to solidify the evaporated materials.

Is my understanding reasonable? Anyone who give me any advises will receive my heartfelt thanks!
