Engineering Grain Boundary Commensurability for Ferroelectric Stabilization in Hafnia-Based Films
Chuqiao Shi, Xinyan Li, Xing He +11
Grain boundaries fundamentally dictate the macroscopic properties of polycrystalline materials by breaking long-range symmetry. In ferroelectrics, these structural discontinuities…
Strong electrostatic control of excitonic features in MoS by a free-standing ultrahigh- ferroelectric perovskite
Thomas Pucher, Sergio Puebla, Victor Zamora +7
We present the electrostatic control of photoluminescence of monolayer MoS at room temperature via integration of free-standing BaTiO (BTO), a ferroelectric perovskite oxid…
A 2D ferroelectric vortex lattice in twisted BaTiO3 freestanding layers
Gabriel Sanchez-Santolino, Victor. Rouco, Sergio. Puebla +10
The wealth of complex polar topologies recently found in nanoscale ferroelectrics result from a delicate balance between the materials intrinsic tendency to develop a homogeneous p…
Strongly anisotropic strain-tunability of excitons in exfoliated ZrSe
Hao Li, Gabriel Sanchez-Santolino, Sergio Puebla +5
We study the effect of uniaxial strain on the band structure of ZrSe, a semiconducting material with a marked in-plane structural anisotropy. By using a modified 3-point bendin…
In-plane anisotropic optical and mechanical properties of two-dimensional MoO
Sergio Puebla, Roberto D'Agosta, Gabriel Sanchez-Santolino +3
Molybdenum trioxide (MoO) in-plane anisotropy has increasingly attracted the attention of the scientific community in the last few years. Many of the observed in-plane anisotro…
Optical microscopy-based thickness estimation in thin GaSe flakes
Wenliang Zhang, Qinghua Zhao, Sergio Puebla +3
We have implemented three different optical methods to quantitatively assess the thickness of thin GaSe flakes transferred on both transparent substrates, like Gel-Film, or SiO2/Si…
Optical-based thickness measurement of MoO nanosheets
Sergio Puebla, Antonio Mariscal-Jiménez, Rosalía Serna Galán +2
Considering that two-dimensional (2D) molybdenum trioxide has acquired more attention in the last few years, it is relevant to speed up thickness identification of this material. W…
Thickness identification of thin InSe by optical microscopy methods
Qinghua Zhao, Sergio Puebla, Wenliang Zhang +3
Indium selenide (InSe), as a novel van der Waals layered semiconductor, has attracted a large research interest thanks to its excellent optical and electrical properties in the ult…
