The quest for solid state non-volatility memory devices on silicon with high
storage density, high speed, low power consumption has attracted intense research
on new materials and novel device architectures. Although flash memory dominates
in the non-volatile memory market currently, it has drawbacks, such as low
operation speed, and limited cycle endurance, which prevents it from becoming the
"universal memory". In this report, we demonstrate ferroelectric tunnel junctions
(Pt/BaTiO3/La0.67Sr0.33MnO3) epitaxially grown on silicon substrates. X-ray
diffraction spectra and high resolution transmission electron microscope images
prove the high epitaxial quality of the single crystal perovskite films grown on
silicon. Furthermore, the write speed, data retention and fatigue properties of
the device compare favorably with flash memories. The results prove that the
silicon-based ferroelectric tunnel junction is a very promising candidate for
application in future non-volatile memories.
