Thermal evaporators of the OEZ type are dedicated to the controlled evaporation of all kind of volatile organic materials. They can be used for research or production of e.g. OLED devices, organic photovoltaic cells, molecular electronics, organic spintronics etc.
The OEZ product line denotes a group of diversiﬁed sources that are all characterized by excellent temperature stability, homogeneous temperature distribution within the crucible and a wide temperature range from 50 to 700 °C.
Quad cell OEZ 40-4x1-12-S: Four 0.2 cm3 crucibles on a single DN40CF (O.D. 2.75‘‘) ﬂange, with integrated water cooling and rotary shutter
For the protection of sensitive research equipment during in situ experiments, specially designed nozzles for single and even dual cells are available (e.g., in situ co-deposition in UHV STM systems).
Optional beam shaping devices allow high ﬁlm thickness homogeneity of the evaporated molecules along with an efﬁcient material utilization. On request the plume shape can be projected by Monte Carlo method simulations.
Depending on the crucible size, OEZ cells can be used for evaporation of small amounts of expensive materials (for fundamental research applications) or deposition of large amounts of organics (in industrial production processes). Crucible replacement is easy and quickly accomplished. While quartz is the preferred material for the evaporation of organics, others like PBN, Alumina, or graphite are available as well.
Various models with single or multiple cells on the same ﬂange ensure adaptability to miscellaneous organic thin ﬁlm applications. The range of crucibles starts with 0.2 cm3 crucibles for small sample preparation in, e.g., surface science and reasonably ends with 25 cm3 crucibles for samples of several inches diameter.
With the rugged and reliable design, inherent to every OEZ, long and stable operation - a basic requirement for industrial and reasearch use - is guaranteed.
