Finite size and intrinsic field effect on the polar-active properties of the ferroelectric-semiconductor heterostructures
A. N. Morozovska, E. A. Eliseev, S. V. Svechnikov +4
Using Landau-Ginzburg-Devonshire approach we calculated the equilibrium distributions of electric field, polarization and space charge in the ferroelectric-semiconductor heterostru…
Non-Collinear Magnetic Phases of a Triangular-Lattice Antiferromagnet and Doped CuFeO
Randy S. Fishman, Satoshi Okamoto
We obtain the non-collinear ground states of a triangular-lattice antiferromagnet with exchange interactions up to third nearest neighbors as a function of the single-ion anisotrop…
Depth-dependent ordering, two-length-scale phenomena and crossover behavior in a crystal featuring a skin-layer with defects
Charo I. Del Genio, Kevin E. Bassler, Aleksandr L. Korzhenevskii +4
Structural defects in a crystal are responsible for the "two length-scale" behavior, in which a sharp central peak is superimposed over a broad peak in critical diffuse X-ray scatt…
Adsorbate-induced Restructuring of Pb mesas Grown on Vicinal Si(111) in the Quantum Regime
Alexander Ako Khajetoorians, Wenguang Zhu, Jisun Kim +4
Using scanning tunneling microscopy and spectroscopy, we demonstrate that the adsorption of a minute amount of Cs on a Pb mesa grown in the quantum regime can induce dramatic morph…
Investigation of Gd3N@C2n (40 < n < 44) family by Raman and inelastic electron tunneling spectroscopy
Brian G. Burke, Jack Chan, Keith A. Williams +7
The structure and vibrational spectrum of Gd3N@C80 is studied through Raman and inelastic electron tunneling spectroscopy (IETS) as well as density functional theory (DFT) and univ…
Raman study of Fano interference in p-type doped silicon
Brian G. Burke, Jack Chan, Keith A. Williams +3
As the silicon industry continues to push the limits of device dimensions, tools such as Raman spectroscopy are ideal to analyze and characterize the doped silicon channels. The ef…
Exchange bias driven by the Dzyaloshinskii-Moriya interaction and ferroelectric polarization at G-type antiferromagnetic perovskite interfaces
Shuai Dong, Kunihiko Yamauchi, Seiji Yunoki +6
Exchange bias is usually rationalized invoking spin pinning effects caused by uncompensated antiferromagnetic interfaces. However, for compensated antiferromagnets other extrinsic…
Pyroelectric response of ferroelectric nanoparticles: size effect and electric energy harvesting
A. N. Morozovska, E. A. Eliseev, G. S. Svechnikov +1
The size effect on pyroelectric response of ferroelectric nanowires and nanotubes is analyzed. The pyroelectric coefficient strongly increases with the wire radius decrease and div…
Magnetic doping of a thiolated-gold superatom
De-en Jiang, Robert L. Whetten
The Au25(SR)18- cluster is a new member in the superatom family which features a centered icosahedral shell (Au13) protected by six RS(AuSR)2 motifs (RS- being a alkylthiolate grou…
A Fast and Efficient Algorithm for Slater Determinant Updates in Quantum Monte Carlo Simulations
Phani K. V. V. Nukala, P. R. C. Kent
We present an efficient low-rank updating algorithm for updating the trial wavefunctions used in Quantum Monte Carlo (QMC) simulations. The algorithm is based on low-rank updating…
Surface Geometric and Electronic Structure of BaFe2As2(001)
V. B. Nascimento, Ang Li, Dilushan R. Jayasundara +15
BaFe2As2 exhibits properties characteristic of the parent compounds of the newly discovered iron (Fe)-based high-TC superconductors. By combining the real space imaging of scanning…
