MBE System for OLEDs

MBE System Description

Multi-chamber system 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 OLED System wtih FTIR


  • 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 ion source and several ports which can be used in the future for other preparation devices. Measurement of surface conductivity possible.
  • Load lock chamber prepared with detachable glove box for either simple sample loading or sample preparation under reduced oxygen and water atmosphere.
