Observing Differential Spin Currents by Resonant Inelastic X-ray Scattering
Yanhong Gu, Joseph Barker, Jiemin Li +12
Controlling spin currents, i.e., the flow of spin angular momentum, in small magnetic devices is the principal objective of spin electronics, a main contender for future energy eff…
Quantum efficiency enhancement of bialkali photocathodes by an atomically thin layer on substrates
Hisato Yamaguchi, Fangze Liu, Jeffrey DeFazio +15
We report quantum efficiency (QE) enhancements in accelerator technology relevant antimonide photocathodes (K2CsSb) by interfacing them with atomically thin two-dimensional (2D) cr…
Free-standing bialkali photocathodes using atomically thin substrates
Hisato Yamaguchi, Fangze Liu, Jeffrey DeFazio +10
We report successful deposition of high quantum efficiency (QE) bialkali antimonide K2CsSb photocathodes on graphene films. The results pave a pathway towards an ultimate goal of e…
In-situ x-ray diffraction and the evolution of polarization during the growth of ferroelectric superlattices
Benjamin Bein, Hsiang-Chun Hsing, Sara J. Callori +4
In epitaxially strained ferroelectric thin films and superlattices, the ferroelectric transition temperature can lie above the growth temperature. Ferroelectric polarization and do…
Engineering polarization rotation in a ferroelectric superlattice
J. Sinsheimer, S. J. Callori, B. Bein +6
A key property that drives research in ferroelectric perovskite oxides is their strong piezoelectric response in which an electric field is induced by an applied strain, and vice-v…
Ferroelectric PbTiO/SrRuO superlattices with broken inversion symmetry
S. J. Callori, J. Gabel, D. Su +3
We have fabricated PbTiO/SrRuO superlattices with ultra-thin SrRuO layers. Due to the superlattice geometry, the samples show a large anisotropy in their electric…
Distribution of Eigenvalues of Real Symmetric Palindromic Toeplitz Matrices and Circulant Matrices
Adam Massey, Steven J. Miller, John Sinsheimer
Consider the ensemble of real symmetric Toeplitz matrices, each independent entry an i.i.d. random variable chosen from a fixed probability distribution p of mean 0, variance 1, an…
