The KNN rollercoaster: from bulk ceramics to phase engineered wafer-scale thin films
Giulia Pavese, Federico Orlando, Fabio Melzi +12
Since the initial disclosure of the extraordinary piezoelectric coefficients of Potassium sodium niobate (KNN) in near-equimolar bulk ceramics, its development trajectory has resem…

Bulk photovoltaic effect in MoSe and Janus MoSSe sliding ferroelectrics
Roumita Roy, Giuseppe Cuono, Silvia Picozzi
We present a first-principles study of the nonlinear optical properties of sliding ferroelectric bilayers based on MoSe and Janus MoSSe. Two Janus configurations are considered…

Bulk photovoltaic effect in ferroelectric and antiferroelectric phases of antimony sulphoiodide investigated by means of ab-initio simulations
Giuseppe Cuono, Subhadeep Bandyopadhyay, Andrea Droghetti +1
We employ first-principles calculations to investigate the ferroelectric properties and the bulk photovoltaic effect (BPVE) of antimony sulfur iodide (SbSI). The BPVE enables direc…
