    Abstract: Exemplary embodiments provide semiconductor devices including high-quality (i.e., defect free) group III-N nanowires and uniform group III-N nanowire arrays as well as their scalable processes for manufacturing, where the position, orientation, cross-sectional features, length and the crystallinity of each nanowire can be precisely controlled. A pulsed growth mode can be used to fabricate the disclosed group III-N nanowires and/or nanowire arrays providing a uniform length of about 10 nm to about 1000 microns with constant cross-sectional features including an exemplary diameter of about 10-1000 nm. In addition, high-quality GaN substrate structures can be formed by coalescing the plurality of GaN nanowires and/or nanowire arrays to facilitate the fabrication of visible LEDs and lasers. Furthermore, core-shell nanowire/MQW active structures can be formed by a core-shell growth on the nonpolar sidewalls of each nanowire.

    Abstract: Une fonction physique non clonable intégrée au «delay embedded hardware» («help puf») tire parti de l'entropie en surveillant la stabilité du trajet et en mesurant les retards du trajet à partir des macros logiques de base. Les techniques d'amélioration de la fiabilité et de la sécurité du help puf réduisent les erreurs de retournement lors de la régénération de la chaîne de bits à travers les variations environnementales et améliorent la résistance cryptographique ainsi que la difficulté correspondante de réaliser des attaques de construction de modèles. Un processus d'inscription basé sur la tension parcourt des chemins instables sur des unités fonctionnelles normalement synthétisées (glitchy) et réduit les erreurs de flip de bit en effectuant l'enrôlement à de multiples tensions d'alimentation contrôlées en utilisant des régulateurs de tension sur puce.

    Abstract: A Hardware-Embedded Delay Physical Unclonable Function ("HELP PUF") leverages entropy by monitoring path stability and measuring path delays from core logic macros. Reliability and security enhancing techniques for the HELP PUF reduce bit flip errors during regeneration of the bitstring across environmental variations and improve cryptographic strength along with the corresponding difficulty of carrying out model building attacks. A voltage-based enrollment process screens unstable paths on normally synthesized (glitchy) functional units and reduces bit flip errors by carrying out enrollment at multiple supply voltages controlled using on-chip voltage regulators.
