quantum dots
Optical gas sensors operating in the mid-infrared region can detect molecules nondestructively and are in increasing demand in various fields. Quantum dots have been used as a means to increase the luminescence intensity. However, the emission wavelength of the fabricated quantum dots is approximately 1.7 µm, and longer wavelengths are needed. A solution to this problem is multilayer stacking of dots. In this study, we investigated the conditions for stacking dots to achieve longer wavelengths by numerical calculations using the effective mass approximation.
