Direct Current Heating

  • Efficient Heating: Direct current flow enables fast temperature ramp-up.
  • Easy Integration: Drawer-style design for seamless UHV system compatibility.
  • High-Temperature Capability: Reaches up to ~1300°C, depending on setup.

  • What is Direct Current Heating?

    Direct current heating, like the name implies, utilizes a direct current through the sample to heat it quickly and efficiently. This heating technique is extremely versatile and can be used in a very wide range of applications, but it requires the sample, or a sample holder with good a good thermal connection to the sample, to be electrically conductive.

    If set-up correctly, Ferrovac direct current heaters can reach temperatures up to ~1300°C.

    The Ferrovac direct current heaters come in the form of a drawer style receiver with electrical connection points that fit the flag style sample plate for DC heating.
    For a complete plug-and-play solution, the direct current heating station provides a fully configured and wired product that can be mounted to a single DN40CF flange.
    These heating stations include a thermocouple, all necessary in-vacuum wiring and electrical feedthroughs, as well as optional linear & rotational motion.

    Typical Applications

    Ferrovac Sample Transporters are available in various configurations to meet a wide range of applications, such as:

    • Semiconductor Surface Preparation: Frequently used in semiconductor research, for processes such as Si(111) 7×7 surface reconstruction.
    • Thin Film Growth & Evaporation: DC heating can serve as a thermal evaporation source for metal deposition in thin film fabrication.
    • Graphene Growth: Heating a metallic substrate (e.g., copper or nickel) to high temperatures to facilitate chemical vapor deposition (CVD) growth of graphene.
    • And much more…

    Heating Station Product Series:

    Heating Station Assembly: The full, ready-to-use heating station that includes vacuum-side wiring, electrical feedthroughs and mounting flange.

    Sample Holder Type: This heating station is compatible with all Ferrovac Flag Style Sample Plates.

    Mounting Flange Size: The entire heating station can be mounted to a single DN40CF flange.

    Heating Stage Version:

    (DC) Version - Fixed Stage
    The stationary heating stage version reaches into the chamber by a customizable distance from the mounting flange.

    (DCMD) Version - Stage with Motion
    This heating stage version is capable of linear & rotary motion. The linear travel and the retracted length can be customized.

    Linear Travel [mm]:

    The maximum travel distance of the manipulator. Added to the retracted length, this defines the shaft's maximum extension into the vacuum chamber.

    Retracted Length / Vacuum-Side Length [mm]:

    Specifies the minimal length of the shaft extending from the DN40CF flange into the vacuum chamber.
