| OEZ thermal evaporators are designed for the controlled evaporation of all types 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 is a group of diversified sources, all characterized by excellent temperature stability, homogeneous temperature distribution within the crucible and a wide temperature range from 50 to 700 °C. Several features and options make the OEZ a workhorse for both research and industrial applications. The PID controlled temperature stability of ±0.05 K allows precise control of the deposition rate. The design effectively eliminates temperature hotspots and overshooting, preventing decomposition of the organic material. |

Optional beam shaping devices allow high film thickness homogeneity of the evaporated molecules along with efficient material utilization.
Depending on the crucible size, OEZ cells can be used for the evaporation of small amounts of expensive materials (for fundamental research applications) or for the deposition of large amounts of organics (in industrial production processes).
Crucible replacement is quick and easy. While quartz is the preferred material for organic evaporation, other materials such as PBN, alumina or graphite are available.
| Different models with single or multiple cells on the same flange ensure adaptability to different organic thin film applications. Crucible sizes range from 0.2 cm3 crucibles for small sample preparation, such as surface science, to 200 cm3 crucibles for samples several inches in diameter. The rugged and reliable design inherent in every OEZ ensures long and stable operation - a basic requirement for industrial and research use. Integrated cell shutters allow controlled sub-monolayer deposition as well as growth of thicker closed films. Automated shutter actuation can be achieved by adding electrical or pneumatic shutter modules to the assembly. For HV applications, ISO-K and KF cells are available as shown in the figure to the right. |
