Design and experimental study of deposition temperature control system in ultra-high vacuum
Deposition temperature is a key factor influencing the growth morphology of thin-films,aiming at this phenomenon,a precise control system of deposition temperature in ultra-high vacuum is developed in the paper.It can realize accurate temperature control in a range of 150K to 450K during experiment by combination of resistance heating up and liquid helium cooling down strategies,which is benefit to further understand the temperature-depended mechanism of organic molecule thin-film growth.Besides,it is experimentally studied that the growth morphology ofp-6p molecules on a mica substrate is closely related to the substrate deposition temperature,indicating that the length of p-6p nano-fibers is proportional to the deposition temperature,while their distribution density is inversely proportional to the temperature.
