Electroluminescence and Franz–Keldysh Modulation Observed in Sn/Ge Multi‐Quantum Wells

open access: yesAdvanced Optical Materials, Volume 14, Issue 9, 6 March 2026.
We investigate the optoelectronic properties of PIN diodes based on ultrathin α‐Sn/Ge multiple quantum film structures, fabricated by molecular beam epitaxy, both experimentally and theoretically. The samples exhibit a light emission spectrum in the short‐wavelength infrared range with two transitions. Furthermore, when operating as a photodetector, we

Si‐Based GeSn Lateral p–i–n Waveguide Photodetectors Covering Entire Short‐Wave Infrared Band

open access: yesAdvanced Photonics Research, Volume 7, Issue 3, March 2026.
This work introduces a complementary metal‐oxide‐semiconductor (CMOS)‐compatible GeSn lateral p–i–n waveguide photodetector monolithically integrated on a silicon platform. Enabled by a high‐quality, and high‐Sn‐content GeSn active layer, the developed GeSn photodetector achieves photodetection covering the entire short‐wave infrared band for ...

Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)

open access: yesAdvanced Science, Volume 13, Issue 15, 13 March 2026.
Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.

FOCUS: A Four‐In‐One Consolidated Unison Strain Sensor with Enhanced Sensitivity

open access: yesAdvanced Science, Volume 13, Issue 14, 9 March 2026.
Through a folding transformation that stacks four printed liquid metal sensors into a unified 3D orthogonal construct, FOCUS harnesses complementary bidirectional resistance responses within a Wheatstone bridge. This architecture yields fivefold sensitivity enhancement and 25 µm resolution, overcoming LM sensors’ micro‐strain limitations and enabling ...
