Custom Research MBE Systems

Advanced yet economical research molecular beam epitaxy - MBE systems for a wide variety of materials growth applications.

Example: Custom Research MBE System for OLEDS

Our research MBE systems are the most economical and versatile systems currently available for R&D and product development. With outstanding levels of automation and sophistication, they deliver results previously only available from systems that are two or three times the price.

The example below is a customised multi-chamber MBE system dedicated for the preparation and investigation of organic films (OLEDs). The XPS analyser and FT-IR unit are third party integrations. Other than these items, every other component, chamber, transfer mechanism, instrument, elctronics unit and software is wholly manufactured by us.

Molecular Beam Epitaxy - MBE Systems

MBE Systems Description

Multi-chamber MBE systems designed around a central radial distribution chamber with attached analytical chambers and auxiliary chambers to fulfill the demands of sample transport under true UHV conditions (pressure lower than 1E-10 mbar). The importance of a very fast and reliable sample transfer is needed because several of the prepared films can only exist at low temperatures. The base pressure in the analytical chambers is < 1E-10 mbar

MBE Systems Highlights

  • Multi-technique analytical chamber integrates different surface analysis methods; X-ray Photoelectron Spectroscopy (XPS), Inverse Photoelectron Spectroscopy (IPES), Ultraviolet Photoelectron Spectroscopy (UPS) and Electron Loss Spectroscopy (EELS).
  • Sample positioning is via a stable, high precision, 4 axis manipulator. The sample receiving station is equipped with a LN2 cryostat that allows temperature variation over the range -180°C to 1000°C (dependent on sample holder used).
  • The Chamber is made from mu-metal and is equipped with a hemispherical analyzer and x-ray source, UV source and low energy electron source. The flexible design allows for easy modification to meet future scientific demands
  • Variable temperature STM/AFM chamber is accessible through a re-orientation chamber directly connected to the distribution chamber. A special sample holder was designed to carry the STM-holder and to allow heating, cooling and temperature measurement of the samples in all of the other chambers
  • Chamber for Infrared Spectroscopy (FT-IR) with commercial IR spectrometer that can be used also in a standalone application. The sample can be heated and cooled during the measurement and the chamber can be equipped with an electron beam evaporator for in-situ sample preparation.
  • Three level preparation chamber, equipped with LEED, TDS, ion source, electron beam evaporator, Knudsen cells, and many ports which can be used in the future for preparation or evaporation devices.
  • Single level preparation chamber equipped with surface conductivity measurement, ion source and several ports which can be used in the future for other preparation devices.
  • Load lock chamber prepared with detachable glove box for either simple sample loading or sample preparation under reduced oxygen and water atmosphere.
