Bias dependent band alignment in Ga<sub>2</sub>O<sub>3</sub> ferroelectric interface by operando HAXPES. [PDF]
Sci RepWe present a fundamental study of the band alignment at the interface of HfZrO4 (HZO) with Ge-doped Ga2O3. Ge is an alternative n-type dopant for the wide band gap Ga2O3 due to its shallow donor level and favorable MBE growth conditions.

Band alignment of rutile and anatase TiO2
Nature Materials, 2013 The most widely used oxide for photocatalytic applications owing to its low cost and high activity is TiO2. The discovery of the photolysis of water on the surface of TiO2 in 19721 launched four decades of intensive research into the underlying chemical and physical processes involved2, 3, 4, 5.

Gamma‐band neural coupling during conceptual alignment
Human Brain Mapping, 2022 AbstractConceptual alignment is a prerequisite for mutual understanding. However, little is known about the neurophysiological brain‐to‐brain underpinning during conceptual alignment for mutual understanding. Here, we recorded multi‐channel electroencephalogram (EEG) simultaneously from two participants in Experiment 1 and adopted the dual‐tACS ...
