The community of material scientists is strongly committed to the research area of
multiferroic materials, both for the understanding of the complex mechanisms supporting the …

Three-dimensional topological insulators are fascinating materials with insulating bulk yet
metallic surfaces that host highly mobile charge carriers with locked spin and momentum …

The ability to assemble layers of two-dimensional (2D) materials to form permutations of van
der Waals heterostructures provides significant opportunities in materials design and …

Dynamical properties of the lattice structure were studied by optical spectroscopy in A Cr 2 O
4 chromium spinel oxide magnetic semiconductors over a broad temperature region of T …

We investigate the shift current bulk photovoltaic response of materials close to a band
inversion topological phase transition. We find that the bulk photocurrent reverses direction …

Topological insulators (TIs) are a new state of quantum matter with a band gap in bulk and
conducting surface states. In this work, the Raman spectra of topological insulator Bi 2 Te 3 …

Copper-doped Bi2Se3 (Cu x Bi2Se3) is of considerable interest for tailoring its electronic
properties and inducing exotic charge correlations while retaining the unique Dirac surface …

We report polarization-resolved Raman scattering measurements on single crystals of the
pyrochlore compound Eu 2 Ir 2 O 7 which exhibits a ground state with noncollinear magnetic …

We present a polarization resolved Raman scattering study of surface vibration modes in the
topological insulator Bi 2 Se 3 single crystal and thick films. Besides the four Raman active …

Understanding exotic, non-s-wave-like states of Cooper pairs is important and may lead to
new superconductors with higher critical temperatures and novel properties. Their existence …
