Stark Tuning of Donor Electron Spins in Silicon
We report Stark shift measurements for 121Sb donor electron spins in silicon
using pulsed electron spin resonance. Interdigitated metal gates on top of a
Sb-implanted 28Si epi-layer are used to apply electric fields. Two Stark
effects are resolved: a decrease of the hyperfine coupling between electron and
nuclear spins of the donor and a decrease in electron Zeeman g-factor. The
hyperfine term prevails at X-band magnetic fields of 0.35T, while the g-factor
term is expected to dominate at higher magnetic fields. A significant linear
Stark effect is also resolved presumably arising from strain.Comment: 10 pages, 4 figures, to be submitted to PR

Energy Efficient All-Electric-Field-Controlled Multiferroic Magnetic Domain-Wall Logic.
Magnetic domain wall (DW)-based logic devices offer numerous opportunities for emerging electronics applications allowing superior performance characteristics such as fast motion, high density, and nonvolatility to process information. However, these devices rely on an external magnetic field, which limits their implementation; this is particularly problematic in large-scale applications. Multiferroic systems consisting of a piezoelectric substrate coupled with ferromagnets provide a potential solution that provides the possibility of controlling magnetization through an electric field via magnetoelastic coupling. Strain-induced magnetization anisotropy tilting can influence the DW motion in a controllable way. We demonstrate a method to perform all-electrical logic operations using such a system. Ferromagnetic coupling between neighboring magnetic domains induced by the electric-field-controlled strain has been exploited to promote noncollinear spin alignment, which is used for realizing essential building blocks, including DW generation, propagation, and pinning, in all implementations of Boolean logic, which will pave the way for scalable memory-in-logic applications
