OTF-1200X-S-HPCVD is a compact 2" split tube furnace with an internal sample traveling system inside the processing tube. This allows the position & temperature control of the sample stage or crucible via touch screen digital controller. It is designed for multi-functional rapid thermal processing, such as hybrid physical-chemical deposition(HPCVD), rapid thermal evaporation (RTE), and as well Horizontal Bridgman Crystal Growth ( HDC) under various atmospheres for new-generation crystal research.

Max. Heating & Cooling Rate
|
The max heating and cooling rate can be achieved by moving the sample into the pre-heated hot zone and moving the sample out from the hot zone. The typical ramp/cool rate is listed in below:
|
Heating Rate:
10°C/sec (150°C - 250°C);
7°C/sec (250°C - 350°C);
4°C/sec (350°C - 500°C);
3°C/sec (500°C - 550°C);
2°C/sec (550°C - 650°C);
1°C/sec (650°C - 800°C);
0.5°C/sec (800°C - 1000°C);

Warning
|
- Tube furnaces with quartz tubes are designed for use under vacuum and low pressure < 0.2 bars / 3 psi
- Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
- Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C

| Application Notes |
This multi-functional furnace is suitable for the applications in below:
- RTE: Crucible loaded with evaporation material is placed in the center of the furnace, and moves sample holder to a downstream position with the appropriate temperature where the deposition takes place.
- HPCVD： Similar setup as RTE, we also introduce reactant gas to mix with evaporation vapor and make a deposition
- Horizontal Bridgman Crystal Growth： Load material and seed into a crucible and place it in the center of the furnace. Move the crucible at the desired speed to grow a single crystal under a suitable thermal gradient.
- If you have any questions or suggestions, please contact us before purchasing
- After CVD, the graphene must be transferred from the metal catalyst to another substrate for most applications. By using the graphene transfer tape, the residue can be low
- For Horizontal directional crystalization (HDC), you may use a gas feedthrough as in the pic below：
