Low Power Consumption Substrate-Emitting DFB Quantum Cascade Lasers

Nanoscale Research Letters, 2017
In the present work, an ultra-low power consumption substrate-emitting distributed feedback (DFB) quantum cascade laser (QCL) was developed. The continuous-wave (CW) threshold power dissipation is reduced to 0.43 W at 25 °C by shortening the cavity ...

A new cohesive model for simulating delamination propagation in composite laminates under transverse loads [PDF]

, 2008
In this paper, we propose a new cohesive model to stably and accurately simulate the\ud delamination propagations in composite laminates under quasi-static and low-velocity\ud impact transverse loads using comparatively coarse meshes.

Superconductivity emerging from a stripe charge order in IrTe2 nanoflakes

Nature Communications, 2021
Superconductivity often appears due to suppression of competing electronic orders. Here, the authors present a contrary example showing a superconducting dome inside the parent phase with a stripe charge order in IrTe2 nanoflakes and identify their ...
