The
MODA Laboratory
MODA stands for "Modular facility for
Oxide Growth and Analyis." It is a complex UHV apparatus allowing for
the fabrication of epitaxial thin films with real-time control of the
growth process and for the in-situcharacterization of the structural ,
electronic and chemical properties of as-grown films by a number of
complementary surface sensitive techniques. A UHV distribution chamber
is employed to transfer the samples between the load-lock fast entry,
the PLD chamber and the analysis chambers.
In brief, MODA allows for:
1) Pulsed laser deposition (PLD) growth of complex oxides films and
multilayers. The PLD chamber includes full automation of deposition
process, due to the software control of sample holder, laser pulses,
gate valves, target carousel, deposition temperature and deposition
pressure.
2) Real time monitoring of the transfer process of atoms, ions and
molecules from the target to the film, in the form of a transient plasma
("plume"). To this aim, we perform fast imaging and spectroscopy of the
plume optical emission at a time resolution scale of the order of
10-100ns.
3) Real time monitoring of the film surface evolution of by high
pressure RHEED (reflection high energy electron diffracion), operating
up to 0.5 mbars.
4) Variable angle photoemission analised with an Omicron Hemisphericl
Analyser using a X-ray Mg, Al twin anode or a UV He lamp as excitation
source.
5) Spot Profile Analysis Low Energy Electron Diffraction (SPA-LEED)
6) Variable Temperature UHV STM/AFM
