Thickness-Dependent Ferroelectricity in Freestanding Hf<sub>0.5</sub>Zr<sub>0.5</sub>O<sub>2</sub> Membranes
In the recent years, ferroelectricity in Hf0.5Zr0.5O2 (HZO) has been intensively studied
due to
its compatibility with silicon-based ferroelectric applications, high
dielectric constant, and maintenance of robust ferroelectricity even
at ultrathin thickness (<10 nm). This makes it a potential alternative
material in ferroelectric field-effect transistors, complementary
metal-oxide-semiconductor (CMOS) gate layers, and other applications.
Previous studies have explained that ferroelectricity is attributed
to the transformation from a tetragonal (t-phase) to orthorhombic
(o-phase) structure during cooling. Conventional HZO thin films that
are directly grown on silicon are polycrystalline, which reduces the
polarization efficiency in CMOS devices. To address this problem,
there is a demand for epitaxial freestanding HZO (FS-HZO) thin films
that can be transferred without substrate constraints. In this study,
we conducted comprehensive analysis of FS-HZO membranes with varying
thicknesses to investigate the relationship between ferroelectric
properties and thin film thickness. With monoclinic phase (m-phase)
substitution, we notice a reduced o-phase fraction and gradual suppression
of ferroelectricity when the thickness is over 20 nm. Owing to the
large structure anisotropy, we further observed an increase in X-ray
linear dichroism with increasing thickness. In addition, the dielectric
constant of FS-HZO decreases by half compared to as-grown HZO due
to increased leakage current from the cracks led by the freestanding
process. This study presents an important method to combine oxides
with silicon-based semiconductors and detailed information on various
thicknesses of FS-HZO in aspects of structure and ferroelectricity,
providing a potential solution to compatibility concerns in the context
of next-generation nanoelectronics
