Services

The Materials Growth Facilities (MGF) is an Institutional Core Research Facility, reporting to the Research Office. We provide a research space which houses two molecular beam epitaxy (MBE) systems connected by a UHV transfer chamber. We conduct calibrations, provide and prep wafers, and offer materials growth on a III-V MBE and Chalcogenide MBE to a diverse research base. A magnetic sputtering system that is UHV connected to both MBEs will be coming online in early 2021. Check out our newest renovations here! Our research tools are available to rent for use by Faculty, Staff, and Graduate students, as well as external academic and non-academic groups. Our Epitaxy Engineer can grow a wide range of materials to requested specifications. Please contact MGF for details below.

Calibrations

The following calibrations are standard. Calibrations outside these standard calibrations may be the responsibility of the group needing them, warrant consideration as a collaborator, or eventually be included as a standard calibration.

III-V MBE

  • GaAs, AlAs, and InAs growth rates
  • GaSb and AlSb growth rates
  • InGaAs lattice-matching (to InP) and growth rate
  • InAlAs lattice-matching (to InP) and growth rate
  • Silicon and beryllium doping in GaAs (generally convertible to other materials)
  • Tellurium doping in GaSb

Chalcogenide MBE

  • Bi2Se3 growth rate
  • Bi2Te3 growth rate
  • In2Se3 growth rate

Growths utilizing our wide range of additional Capabilities can be calibrated to specific user needs or performed on a “best effort” basis.

For additional details, see our MGF Procedures or contact us (below).

 

Wafers

The MGF stocks several wafer types which are available to users at cost.

  • 2” GaAs (001-oriented, semi-insulating)
  • 2” GaAs (001-oriented, n-type)
  • 2” InP (001-oriented, semi-insulating)
  • 2” InP (001-oriented, n-type)
  • 1cm x 1cm c-plane sapphire
  • Other wafers may be used with approval

Costs

Costs are based on operational expenses for the facility and requirements to remain a federally compliant service center.

User fees are set on a per-day basis and are inclusive of source material and liquid nitrogen but exclusive of wafers. Staff-assisted days are indivisible units. Independent users can split a day amongst themselves, but full days must be reserved in all cases.

CHARACTERIZATION

The Epitaxy Engineer can perform sample characterization, using many of the facilities available at UD. When staff-assisted time that does not involve growth on an MBE is required, user fees are set on an hourly basis.
