摘要: In this letter, we report the growth of self-assembled, catalyst-free InP nanoneedles on Si substrate by low-temperature metal-organic chemical vapor deposition. With a characteristic core-shell mode, nanostructure size is scalable with time, and InP/InGaAs/InP double-heterostructure demonstrated. Single crystalline wurtzite essentially free stacking faults polytypism are achieved. The internal quantum efficiency as-grown unpassivated can reach as high 15% at room temperature. Laser oscillation realized from single nanoneedle under optical pump. These promising results reveal potential integrating optoelectronic devices traditional silicon.
