Charge-polarization coupling in the nanostructure "thin HfZrO film - graphene"
To describe the charge-polarization coupling in the nanostructure formed by a
thin HfZrO film with a single-layer graphene as a top
electrode, we develop the phenomenological effective Landau-Ginzburg-Devonshire
model. This approach is based on the parametrization of the Landau expansion
coefficients for the polar and antipolar orderings in thin
HfZrO films from a limited number of polarization-field curves
and hysteresis loops. The Landau expansion coefficients are nonlinearly
dependent on the film thickness and Zr/[Hf+Zr] ratio , in contrast to
h-independent and linearly -dependent expansion coefficients of a classical
Landau energy. We explain the dependence of the Landau expansion coefficients
by the strong nonmonotonic dependence of the HfZrO film polar
properties on the film thickness, grain size and surface energy. The proposed
Landau free energy with five "effective" expansion coefficients, which are
interpolation functions of and , describes the continuous transformation
of polarization dependences on applied electric field and hysteresis loop
shapes induced by the changes of and in the range and 5 nm
< < 35 nm. Using this effective free energy, we demonstrated that the
polarization of HfZrO film influences strongly on the graphene
conductivity, and the full correlation between the distribution of polarization
and charge carriers in graphene is revealed. In accordance with our modeling,
the polarization of the (5 - 25) nm thick HfZrO films, which
are in the ferroelectric-like or antiferroelectric-like states for the chemical
compositions , determine the concentration of carriers in
graphene and can control its field dependence. The result can be promising for
creation of next generation Si-compatible nonvolatile memories and
graphene-ferroelectric FETs.Comment: 30 pages including 8 figures and 1 Appendix with 2 figure
Family Members\u27 Influence on Family Meal Vegetable Choices
Objective—Characterize the process of family vegetable selection (especially cruciferous, deep orange, and dark green leafy vegetables); demonstrate the usefulness of Exchange Theory (how family norms and past experiences interact with rewards and costs) for interpreting the data.
Design—Eight focus groups, two with each segment (men/women vegetable-likers/dislikers based on a screening form). Participants completed a vegetable intake form.
Setting—Rural Appalachian Pennsylvania.
Participants—61 low-income, married/cohabiting men (n=28) and women (n=33).
Analysis—Thematic analysis within Exchange Theory framework for qualitative data. Descriptive analysis, t-tests and chi-square tests for quantitative data.
Results—Exchange Theory proved useful for understanding that regardless of sex or vegetable liker/ disliker status, meal preparers see more costs than rewards to serving vegetables. Past experience plus expectations of food preparer role and of deference to family member preferences supported a family norm of serving only vegetables acceptable to everyone. Emphasized vegetables are largely ignored due to unfamiliarity; family norms prevented experimentation and learning through exposure.
Conclusions and Implications—Interventions to increase vegetable consumption of this audience could 1) alter family norms about vegetables served, 2) change perceptions of past experiences, 3) reduce social and personal costs of serving vegetables and 4) increase tangible and social rewards of serving vegetables
