Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor
Advanced Functional Materials, EarlyView.Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling

James Baldwin: Biographical Dispatches on a Freedom Writer
James Baldwin Review, 2016 This essay presents the idea of James Baldwin as a freedom writer, the organizing idea of my biography in progress. As a freedom writer, Baldwin was a revolutionary intellectual, an essayist and novelist committed unfailingly to the realization of racial

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies
Advanced Functional Materials, EarlyView.The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

Advanced Functional Materials, EarlyView.ABSTRACT Perovskite solar cells (PSCs) are promising next‐generation photovoltaics. The high performance of PSCs is attributed to the long carrier lifetimes of perovskite photoabsorbers. However, the carrier lifetimes of polycrystalline perovskite layers, which serve as the photoabsorbers in practical PSCs, have remained limited to several tens of ...

Wigner crystals: New realizations of an old idea [PDF]
EPJ Web of Conferences, 2014 In this review, after a brief discussion of Wigner’s ideas about the localization of electrons due to Coulomb interaction in a low-density electron system with neutralizing background and the formation of a periodic array, we present the various possibilities to realize Wigner crystals: on the surface of liquid helium, in semiconductor heterostructures,
