Al1−xHfxN$\text{Al$_{1-x}$Hf$_{x}$N}$ Thin Films with Enhanced Piezoelectric Responses for GHz Surface Acoustic Wave Devices

Advanced Electronic Materials, EarlyView.
Reactively sputtered wurtzite Al1‐xHfxN thin films, exhibiting strong c‐axis texture and enhanced piezoelectric response, are demonstrated as a cost‐effective alternative to Al1‐xScxN. X‐ray absorption spectroscopy reveals that cross‐gap N 2p–Hf 5d hybridization increases the Born effective charge and enables a multifold increase in piezoelectric ...

On the Impact of Mechanical Constraint on Band Structure and Photo‐Elastic Effect in Photonic Resonators

Advanced Physics Research, EarlyView.
We computationally investigate the mechanical, electronic, and optical properties of strained GeSn microdisks on silicon substrates. By combining photo‐elasticity, strain‐dependent band‐structure calculations, and optical mode analysis, we study how strain distribution, structural configuration, and temperature affect the electronic band structure and ...
