Thin Film Substrates from the Raman spectroscopy point of view

L. Gasparov, T. Jegorel, L. Loetgering +2

We have investigated ten standard single crystal substrates of complex oxides on the account of their applicability in the Raman spectroscopy based thin film research. In this stud…

Terahertz dielectric response and coupled dynamics of ferroelectrics and multiferroics from effective Hamiltonian simulations

Dawei Wang, Jeevaka Weerasinghe, Abdullah Albarakati +1

Ferroelectric and multiferroic materials form an important class of functional materials. Over the last twenty years, first-principles-based effective Hamiltonian approaches have b…

Condensation of the atomic relaxation vibrations in lead-magnesium-niobate at

Sergey Prosandeev, Igor P. Raevski, Maria A. Malitskaya +4

We present neutron diffraction, dielectric permittivity and photoconductivity measurements, evidencing that lead-magnesium niobate experiences a diffuse phase transformation betwee…

Natural optical activity and its control by electric field in electrotoroidic systems

Sergey Prosandeev, Andrei Malashevich, Zhigang Gui +4

We propose the existence, via analytical derivations, novel phenomenologies, and first-principles-based simulations, of a new class of materials that are not only spontaneously opt…

Molecular Beam Epitaxial Growth of Bi2Te3 and Sb2Te3 Topological Insulators on GaAs (111) Substrates: A Potential Route to Fabricate Topological Insulator p-n Junction

Zhaoquan Zeng, Timothy A. Morgan, Dongsheng Fan +11

High quality Bi2Te3 and Sb2Te3 topological insulators films were epitaxially grown on GaAs (111) substrate using solid source molecular beam epitaxy. Their growth and behavior on b…
