EPSRC Doctoral Landscape Award 2026/27: Electronic & Electrical Engineering - Carrier transport modelling in group-IV SiGeSn quantum well semiconductor lasers

This PhD research opportunity focuses on carrier transport modelling in multiple quantum well (MQW) laser structures using group-IV SiGeSn semiconductors. The project aims to advance the development of electrically pumped lasers operating at room temperature, which would enable monolithic integration of group-IV based photonics and CMOS technology. The research will model carrier trapping and transport in quantum wells to achieve homogeneous distribution of electrons and holes across MQW structures, using methodologies adapted from III-V semiconductor lasers. The work involves calculating electronic structures of SiGeSn-based MQWs and designing optimal well and barrier configurations within practical material composition constraints. This represents a pathway toward overcoming the indirect bandgap limitation of conventional silicon and germanium semiconductors for large-scale optoelectronics integration.
