However, achieving electrically excited amplified spontaneous emission (ASE) in perovskite light-emitting diodes (PeLEDs), a pre-condition for perovskite laser diodes, is hindered by the conflicting requirements of high conductivity and high net modal gain of the device stack. Here we develop a ...
For example, the α and β absorption bands in alkali halides correspond to exciton formation around an anion vacancy and an F-center, respectively. Shallow bound excitons, as are realized at donors in direct gap semiconductors (such as CdS), have large oscillator strengths of the order of ...
Specify the algorithm parameters , maximum iteration (TMaxIter), agent population w and system parameters like number of thermal units N, capacity limits, cost and emission coefficients of the thermal units, scheduling hour (T), real power load requirements, and transmission loss matrix B-coefficien...

Flexible expansion: the system can monitor sulfur dioxide, nitrogen oxides, particulate matter and the parameters of flue gas, and can also be customized according to the monitoring requirements of different customers; Automation and intellectualization: it can realize the automatic unmanned operation of...
goals. Instead, the focus was on defining a clear interface between LCI and LCIA. This should be capable of supporting any goal and scope requirements while avoiding double counting or excluding important emission flows (and their potential impacts). The detailed recommendations are given in section...
Thus, AE source identification requires analysis of frequency spectra, whereby the weighted peak frequency (WPF) is found to be the most characteristic feature of a spectrum combining peak frequency and center of gravity in a single figure [14]. In case of brittle cracks, large and rapid ...
(accounting for 3–4% of the total thermal power capacity from 2014 to 2017) because their furnaces did not meet the requirements necessary to install a CEMS. For the power plants outside the CEMS network, we assume their stack concentrations are similar to the averages of the units with ...
Here we show that a delicately designed metallic sawtooth nanoslit array, whose configuration supports plasmonic resonances strongly polarized along the long axis of the array, fulfills all the above requirements. In particular, strong resonant transmission can be excited at different wavelengths and pre...
