The low temperature corrections to the Casimir force between a sphere and a plane

open access: yes, 2010
We calculate the low temperature corrections to the free energy for a sphere in front of a plane. First, the scalar field obeying Dirichet or Neumann boundary conditions is considered.

Domain Nucleation and Growth in an Epitaxially Grown Wurtzite Ferroelectric

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectric domain nucleation and growth in epitaxial wurtzite (Al, B, Sc)N films are visualized through in situ transmission electron microscopy. Domains initiate near the bottom electrode and propagate laterally with zigzag walls, while unswitched regions remain near the electrode interfaces.

Infrared and THz studies of polar phonons and improper magnetodielectric effect in multiferroic BFO3 ceramics

open access: yes, 2006
BFO3 ceramics were investigated by means of infrared reflectivity and time domain THz transmission spectroscopy at temperatures 20 - 950 K, and the magnetodielectric effect was studied at 10 - 300 K, with the magnetic field up to 9 T.

Molecularly Tailored Elastomeric Block‐Copolymers for Intrinsically Stretchable Organic Field‐Effect Transistors

open access: yesAdvanced Functional Materials, EarlyView.
Molecular‐level engineering of SEBS elastomers is introduced for skin‐inspired electronics. By systematically modulating the S/EB molar ratio in SEBS, precise control is achieved over nanoscale morphology, mechanical properties, metal‐elastomer adhesion, and dielectric performance.

Temperature Dependent Polarity Reversal in Au/Nb:SrTiO3 Schottky Junctions

open access: yes, 2007
We have observed temperature-dependent reversal of the rectifying polarity in Au/Nb:SrTiO3 Schottky junctions. By simulating current-voltage characteristics we have found that the permittivity of SrTiO3 near the interface exhibits temperature dependence ...
