Especially, GeSn-based Group-IV alloys have demonstrated a direct band gap with higher electron mobility, which is beneficial for photonic integrated chips (PIC) and spintronic fields with complementary metal-oxide semiconductor (CMOS) compatibility.[1] A recent breakthrough in the Si photonics field was the demonstration of continuous-wave, electrically pumped lasing based on advanced SiGeSn/GeSn multi-quantum well structures (MQWs).[2] In addition, theoretical calculations predict that C substitution into the Ge and GeSn lattice further improves the fundamental bandgap directness, enhancing laser performance.[3] Moreover, incorporating C as well as Si and Sn into Ge allowed a large tunability of the light emission in the Mid-infrared range of 2-5 μm. However, the low solid solubility and large lattice mismatch mostly limit the substitutional incorporation of C into the Ge diamond lattice. 001053152 536__ $$0G:(DE-HGF)POF4-5234$$a5234 - Emerging NC Architectures (POF4-523)$$cPOF4-523$$fPOF IV$$x0 001053152 536__ $$0G:(EU-Grant)101070208$$aLASTSTEP - group-IV LASer and deTectors on Si-TEchnology Platform (101070208)$$c101070208$$fHORIZON-CL4-2021-DIGITAL-EMERGING-01$$x1 001053152 65027 $$0V:(DE-MLZ)SciArea-180$$2V:(DE-HGF)$$aMaterials Science$$x0 001053152 65017 $$0V:(DE-MLZ)GC-2004-2016$$2V:(DE-HGF)$$aBasic research$$x0 001053152 7001_ $$0P:(DE-HGF)0$$aConcepción, O.$$b1 001053152 7001_ $$0P:(DE-Juel1)186980$$aLiu, Teren$$b2 001053152 7001_ $$0P:(DE-HGF)0$$aSeidel, L.$$b3 001053152 7001_ $$0P:(DE-Juel1)177006$$aBae, J.
