This Special Section of physica status solidi (a) covers presentations Symposium I held at the 2022 Fall-EMRS Meeting in Warsaw, Poland. Group-IV semiconductors, namely Si, Ge, Sn and their compounds, are most important materials micro- nanoelectronics but they will also play a key role future quantum devices. symposium aimed to share latest research field group-IV nanoelectronic Silicon (Si) i...

Laser micro-welding is an advanced manufacturing method today applied in various domains. However, important physical limitations have prevented so far to demonstrate its applicability silicon (Si) and other technology-essential semiconductors. Concentrating on circumventing the optical limits deliverable energy density at interfaces between narrow-gap materials with intense infrared light, fir...

Monolayer transition metal dichalcogenides with direct bandgaps are emerging candidates for microelectronics, nano-photonics, and optoelectronics. Transferred onto photonic integrated circuits (PICs), these semiconductor materials have enabled new classes of light-emitting diodes, modulators photodetectors, that could be amenable to wafer-scale manufacturing. For devices, the optical losses PIC...
