Abstract

Efficient heat dissipation that can minimize temperature increases in device is critical in realizing electrical injection lasers. High-thermal-conductivity diamonds are promising for overcoming heat dissipation limitations for perovskite lasers. In this study, we demonstrate a perovskite nanoplatelet laser on a diamond substrate that can efficiently dissipate heat generated during optical pumping. Tight optical confinement is also realized by introducing a thin SiO2 gap layer between nanoplatelets and the diamond substrate. The demonstrated laser features a Q factor of ∼1962, a lasing threshold of 52.19 µJ cm−2, and a low pump-density-dependent temperature sensitivity (∼0.56 ± 0.01 K cm2... (More)

The demonstrated laser features a Q factor of ∼1962, a lasing threshold of 52.19 µJ cm−2, and a low pump-density-dependent temperature sensitivity (∼0.56 ± 0.01 K cm2 µJ−1) through the incorporation of the diamond substrate. We believe our study could inspire the development of electrically driven perovskite lasers. [Figure not available: see fulltext.].
