چکیده
Light Polarization Control In article number 2208825, Xia Hong and co-workers describe how heterostructures composed of noncentrosymmetric 2D MoS2 free-standing ferroelectric oxide membranes provide a versatile material platform for realizing in operando programming nonlinear light via nanoscale domain patterning, which can be used developing flexible optoelectronics smart optical information processing.

Imaging and Control of Domain Structures in Ferroelectric Thin Films via Scanning Force Microscopy1
Scanning force microscopy (SFM) is becoming a powerful technique with great potential both for imaging and for control of domain structures in ferroelectric materials at the nanometer scale. Application of SFM to visualization of domain structures in ferroelectric thin films is described. Imaging methods of ferroelectric domains are based on the detection of surface charges in the noncontact mo...
متن کاملInteraction between Ferroelectric Polarization and Defects in BiFeO3 Thin Films
Nanoscale impurity defects, with structures different from host materials, are known to commonly exist in functional complex oxides as a result of slight stoichiometry fluctuations that occur during material growth. Local perturbations induced by these defects, such as charge, strain, and atomic interaction, could have a profound effect on the physical properties of oxide nanomaterials. A direc...
متن کاملFlexoelectric rotation of polarization in ferroelectric thin films.
Strain engineering enables modification of the properties of thin films using the stress from the substrates on which they are grown. Strain may be relaxed, however, and this can also modify the properties thanks to the coupling between strain gradient and polarization known as flexoelectricity. Here we have studied the strain distribution inside epitaxial films of the archetypal ferroelectric ...
متن کاملIdeal barriers to polarization reversal and domain-wall motion in strained ferroelectric thin films
The ideal intrinsic barriers to domain switching in c-phase PbTiO3 PTO , PbZrO3 PZO , and PbZr1−xTixO3 PZT are investigated via first-principles computational methods. The effects of epitaxial strain on the atomic structure, ferroelectric response, barrier to coherent domain reversal, domain-wall energy, and barrier to domain-wall translation are studied. It is found that PTO has a larger polar...
متن کاملFerroelectric Polarization in Nanocrystalline Hydroxyapatite Thin Films on Silicon
Hydroxyapatite nanocrystals in natural form are a major component of bone--a known piezoelectric material. Synthetic hydroxyapatite is widely used in bone grafts and prosthetic pyroelectric coatings as it binds strongly with natural bone. Nanocrystalline synthetic hydroxyapatite films have recently been found to exhibit strong piezoelectricity and pyroelectricity. While a spontaneous polarizati...
