▎ 摘 要
NOVELTY - Vertical tube furnace comprises a furnace body, the furnace body is provided with process cabin, a transition chamber is disposed above or below the furnace body, the transition chamber being configured to be in communication with process chamber and capable of being turned off, a pylon disposed in the process chamber for placing a growth substrate and moving the device to move the pylon back and forth between the process chamber and the transition chamber. USE - The furnace is useful for growing graphene (claimed). ADVANTAGE - The furnace improves film quality of the graphene. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic representation of the vertical tube furnace
