GeSn Quantum Wells for Room‐Temperature Mid‐Infrared Lasing on Si and on Insulator Platforms

open access: yesAdvanced Optical Materials, EarlyView.
This work demonstrates a high‐performance GeSn‐on‐Insulator (GeSnOI) platform achieving laser emission up to room temperature. By utilizing Group IV GeSn quantum well heterostructures, we successfully reached a target wavelength of 3.3 µm. This advancement paves the way for fully integrated Mid‐IR photonic CMOS‐compatible sources, overcoming the ...

Price Desclosure, Marginal Abatement Cost Information and Market Power in a Bilateral GHG Emissions Trading Experiment. [PDF]

open access: yes
We conducted an experiment to examine the performance of the bilateral trading institution in GHG emissions trading. First, we found that the efficiency of bilateral trading is quite high, regardless of the disclosure or closure of contracted price and ...

High Efficiency 3‐Tandem Top Emitting Pure‐Blue OLEDs Beyond the BT.2020 Blue Standard

open access: yesAdvanced Optical Materials, EarlyView.
We report a high‐efficiency ultrapure‐blue 3‐tandem TEOLED through synergistic optimization of a narrowband MR‐TADF emitter, Purcell‐based cavity design, and pure Ag cathode/CPL structure. The optimized device achieves 463 nm emission, an ultranarrow FWHM of 10 nm, CIE y of 0.040, and a blue index of 1,596 cd/A/y, surpassing the BT.2020 blue standard ...

Who would get Gains from EU's Quantity Restraint on Emissions Trading in the Kyoto Protocol?. [PDF]

open access: yes
The EU proposal on the quantity restraint of the emissions trading in the Kyoto Protocol aims at reducing the so called hot air that would be generated by the purchase of emissions permits sold by a country whose actual emissions are much lower than the ...

An AI‐Enabled All‐In‐One Visual, Proximity, and Tactile Perception Multimodal Sensor

open access: yesAdvanced Robotics Research, EarlyView.
Targeting integrated multimodal perception of robots, an AI‐enabled all‐in‐one multimodal sensor is proposed. This sensor is capable of perceiving three types of modalities, including vision, proximity, and tactility. By toggling an ultraviolet light and adjusting the camera focus, it switches smoothly between multiple perceptual modalities, enabling ...
