It is well known that periodic discrete defect-containing systems support both traveling
waves and vibrational defect-localized modes. It turns out that if a periodic discrete system is …

Relaxor ferroelectricity is one of the most widely investigated but the least understood
material classes in the condensed matter physics. This is largely due to the lack of …

Lead-free dielectric capacitors with high energy storage density and temperature-insensitive
performance are pivotal to pulsed power systems. In this work, a pronounced recoverable …

The intricacies in identifying the appropriate material system for energy storage applications
have been the biggest struggle of the scientific community. Countless contributions by …

Molecular-dynamics method is used to study the influence of mass ratio of anions and
cations on the phonon spectrum of the crystal with NaCl structure and on the conditions of …

A density functional theory (DFT) study of the discrete breathers (DBs) in graphane (fully
hydrogenated graphene) was performed. To the best of our knowledge, this is the first …

Relaxor-based ferroelectrics are prized for their giant electromechanical coupling and have
revolutionized sensor and ultrasound applications. A long-standing challenge for …

Relaxor ferroelectrics exemplify a class of functional materials where interplay between
disorder and phase instability results in inhomogeneous nanoregions. Although known for …

Uranium is an important radioactive material used in the field of nuclear energy and it is
interesting from the scientific point of view because it possesses unique structure and …

Abstract The lead-free 0.96 NaNbO 3-0.04 CaSnO 3 ceramics with rare-earth dopants (La,
Sm and Lu)(NCLn100x) were prepared and characterized. It is found that a certain amount …
