Defect‐Control Strategies for III–V Heteroepitaxy on Silicon
In silicon photonics, the direct heteroepitaxy of III–V materials on Si is a highly promising route toward on‐chip integration of high‐density active optoelectronic devices. However, an inherent conflict persists between the high threading dislocation density (TDD) created by lat...
