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…
