Quantum spin Hall transport in InAs/GaInSb-based two-dimensional topological insulators can be limited by parasitic bulk and edge contributions. We demonstrate that these limitations are effectively mitigated through electrostatic control in dual-gated InAs/GaInSb/InAs trilayer quantum wells grown on AlSb quasi-substrates. In macroscopic Hall …

The dislocation dynamics in epitaxially strained GaSb/AlSb/GaSb heterostructures grown on a Si(001) substrate via molecular beam epitaxy have been studied by means of scanning transmission electron microscopy. The 100 nm-thick AlSb layer – intentionally inserted as dislocation filter – is partially relaxed …

This study presents the integration of an Interband Cascade Laser (ICL) source emitting at 4 µm onto a silicon-germanium photonic platform, achieved through the Micro-Transfer Printing (µTP) technique. To our knowledge, this study reports the first demonstration of an integrated mid-infrared laser …

Overcoming the limitations of the von Neumann architecture requires new computational paradigms capable of solving complex problems efficiently. Quantum and neuromorphic computing rely on unconventional materials and device functionalities, yet achieving resilience to imperfections and reliable operation remains a major challenge. This …

Semiconductor photonic devices operating in the midwave infrared (mid-IR, which we roughly define here as wavelengths spanning 3 to 14 µm) uniquely address a wide range of current practical needs. These include chemical sensing, environmental monitoring, industrial process control, medical diagnostics, thermal …
