A portable MBE system for in situ X-Ray investigations at synchrotron beamlines
A portable synchrotron MBE system is designed and applied for in situ
investigations. The growth chamber is equipped with all the standard MBE
components such as effusion cells with shutters, main shutter, cooling shroud,
manipulator, RHEED setup and pressure gauges. The characteristic feature of the
system is the beryllium windows which are used for in situ x-ray measurements.
An UHV sample transfer case allows in-vacuo transfer of samples prepared
elsewhere. We describe the system design and demonstrate it's performance by
investigating the annealing process of buried InGaAs self organized quantum
dots
