Anisotropically biaxial strain in non-polar (112–0) plane In x Ga1−x N/GaN layers investigated by X-ray reciprocal space mapping

Scientific Reports, 2017
In this study, the indium composition x as well as the anisotropically biaxial strain in non-polar a-plane In x Ga1−x N on GaN is studied by X-ray diffraction (XRD) analysis. In accordance with XRD reciprocal lattice space mapping, with increasing indium

Complex Cryptographic and User‐Centric Physically Unclonable Functions Enabled by Strain‐Sensitive Nanocrystals via Selective Ligand Exchange

Advanced Functional Materials, EarlyView.
This study investigates electromechanical PUFs that improve on traditional electric PUFs. The electron transport materials are coated randomly through selective ligand exchange. It produces multiple keys and a key with motion dependent on percolation and strain, and approaches almost ideal inter‐ and intra‐hamming distances.
