Hard x-ray photoelectron spectroscopy (HAXPES) is establishing itself as an essential
technique for the characterisation of materials. The number of specialised photoelectron …

BiFeO3-based heterostructures have attracted much attention for potential applications due
to their room-temperature multiferroic properties, proper band gaps and ultrahigh …

In the brain, learning is achieved through the ability of synapses to reconfigure the strength
by which they connect neurons (synaptic plasticity). In promising solid-state synapses called …

Strong electronic correlations can produce remarkable phenomena such as metal–insulator
transitions and greatly enhance superconductivity, thermoelectricity or optical nonlinearity. In …

The discovery of ferroelectricity in polycrystalline thin films of doped HfO2 has reignited the
expectations of developing competitive ferroelectric non-volatile memory devices. To date, it …

The superior size and power scaling potential of ferroelectric-gated Mott transistors makes
them promising building blocks for developing energy-efficient memory and logic …

Photoelectron spectroscopy has its roots in the Nobel Prize-winning work of Albert Einstein
and Kai Siegbahn. It is therefore both an honor and a humbling experience to produce a …

Ferroelectric interfacial devices consist of materials systems whose interfacial electronic
properties (such as a 2D electron gas or an interfacial magnetic spin configuration) are …

We review the concept of surface charge, first, in the context of the polarization in
ferroelectric materials and, second, in the context of layers of charged ions in ionic …

When electrons tunnel through an ultrathin ferroelectric, large variations of the tunnel
transmission can result from the switching of the ferroelectric polarization. High‐quality …
