abstract = {Rational design and implementation of new generations of
functional materials for energy conversion and storage,
requires better fundamental understanding of these systems
along with the ability to predict their properties
accurately. [1, 2, 3] Utilizing thin film systems, the
knowledge of the driving parameters to obtain them in high
quality is crucial [4]. Molecular Beam Epitaxy (MBE) proves
to be a versatile method to grow high quality and high
purity epitaxial films with low intrinsic defect
concentrations and atomic-layer control.At the JCNS thin
film laboratory, we run an oxide MBE system for the growth
of various types of samples, i.e. “classical” magnetic
thin films, transition metal oxide heterostructures or just
thin gold films for soft matter studies, acting as defined
surfaces. However, every sample system comes with its own
challenges which makes thin film growth a research topic on
its own.In the presentation, we will give an overview for
high quality metal and complex oxide thin film systems all
fabricated in the JCNS thin film laboratory, like SrCoOx,
La1-xSrxMnO3, Fe4N or Cu/Fe multilayers. The focus lies on
stoichiometry, morphology and thickness precision and
detailed information about the possibilities in sample
fabrication for users will be given.For quasi in-situ
neutron reflectometry on thin films which are sensitive to
ambient air a small versatile transfer chamber can be
utilized for sample transfer and measurement from the MBE
laboratory to the neutron instrument MARIA [5]. Both, the
MBE setup and the transfer chamber may be booked in
combination with an application for beam time at neutron
instruments like MARIA.[1] R. Waser, Nanoelectronics and
