Introduction:
PT-1200X is a compact 1100°C CVD tube furnace with precursor sublimating attachment. Totally four-channel gas inlets are built on the sublimation which allows feedings of various gases to carry the source vapor into the main heater for further decomposition and deposition. The sample holder fixture mounted on the right flange is slidable for easy sample loading/unloading. Such a system configuration is suitable for growing a wide range of transitional metal dichalcogenides (such as MoSe2, MoS2...) and wide bandgap semiconductors (such as h-BN) layers on substrate up to 3" diameter.

Furnace and Preheater |
Compact CVD furnace system is modified from PT-1200X-100 single zone tube furnace: · 4.33" O.D x 4.05" I.D x 29.13" Length quartz tube · 1100ºC Max. working temperature · Water cooling flange on right-side is slidable for easy sample loading · Water cooling flange on left-side between the heater and furnace is used for pre-heated gas input and sealing Four-channel gas inlet ( 1/8" Dia tube and tube fitting) are built-in on the left side flange One small heater is attached to the left side flange of the furnace to preheat input gas, liquid, or evaporate solid chemical, which will be then delivered to CVD furnace: · Please click picture left for more details: · Flange on the left side is for gas sealing and input |

· The tube furnaces with quartz tube are designed for use under vacuum and low pressure <0.2 bars · Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. · Vacuum pressures may only be safely used up to 1000°C · The flow rate for gasses should be limited to< 200ml/min) for reducing thermal shocks to the tube |
