19 mW/μm² and 24.5 % PAE at 94 GHz for 0.30-μm Transferred InP/GaAsSb DHBT on Si-HR

Abdelmalek Zemour, Malek Zegaoui, Yannick Roelens, Etienne Okada, Pascal Chevalier, Mohammed Zaknoune

InP HBT technology is a suitable candidate for the future 6G networks that require very high bandwidth. It has already demonstrated high-frequency operation with fmax exceeding 1 THz [1]. However, this performance comes at the cost of aggressive scaling which increases thermal resistance (Rth) due…

A unified Eshelbian-like determination of defect driving forces

Stefano Giordano, Claudia Binetti, Giuseppe Puglisi, Salvatore Di Stefano

Within the framework of Continuum Mechanics, we present a unified theoretical approach to describe the onset and propagation of defects in solid materials. In this context, the term defect encompasses both changes in the material’s topology—such as fracture propagation, rotation, and volumetric…

A multiscale approach to investigate the impact of thermal fluctuations on crack propagation in fracture and decohesion

Claudia Binetti, Giuseppe Florio, Nicola M Pugno, Stefano Giordano, Giuseppe Puglisi

In various physical, biological and technological systems, fracture propagation and decohesion phenomena are widespread. Understanding these processes has broad applications, ranging from classical solid mechanics (e.g., crack propagation) to emerging fields such as advanced materials,…
