Semiconductor grafting enables GaAs/GeSn-MQW/Ge photodiode integration
—
What the study found A lattice-mismatched GaAs/GeSn-multi-quantum well (MQW)/Ge n-i-p heterojunction photodiode was realized using semiconductor grafting. The device showed a record-low dark current density, broad spectral response, and high photoresponsivity. Why the authors say this matters The authors conclude that this grafting approach provides a way to build optoelectronic heterojunctions without the usual strict…
Tetraethynyl DOTs show π-stacking and n-type semiconductor behavior
—
in ChemistryTetraethynyl dioxotriangulene derivatives synthesized via C–O activation demonstrate n-type semiconductor properties through π-stacking and radical anion stabilization in field-effect transistors.
CaCd2P2 stays stable under alkaline water oxidation
CaCd2P2 Zintl phosphide absorbs visible light and resists photocorrosion through light-stabilized surface transformation, enabling stable photoelectrochemical water oxidation for solar fuel.
