Spectroscopic studies of excitonic materials for optoelectronic devices

正在重塑加拿大日常生活的主要技术趋势-从云计算，可再生能源和远程医疗到社交媒体，智能手机和物联网-都建立在数万亿传输和转换能源和信息的电子设备上。目前，这些组件（晶体管、探测器、光电二极管、LED……）绝大多数都是由传统的半导体，特别是硅制成的。然而，在某些应用中，替代材料具有现实优势，包括能源效率，灵活性或独特的性能。事实上，在2016年，大多数高端智能手机显示屏都是由分子有机半导体制成的，顶级平板电视采用胶体量子点--色彩鲜艳的半导体块。

The major technological trends that are reshaping everyday life in Canada—from cloud computing, renewable energy, and telemedicine, to social media, smartphones, and the internet-of-things—are built upon the trillions of electronic devices that transmit and transform energy and information. At present, these components (transistors, detectors, photovoltaics, LEDs...) are overwhelmingly made from traditional semiconductors, particularly silicon. However, in some applications, alternative materials have real-world advantages, including energy efficiency, flexibility, or unique performance. Indeed, in 2016, most high-end smartphone displays are made from molecular organic semiconductors, and top-of-the-line flat-panel televisions employ colloidal quantum dots—brilliantly colourful semiconductor chunks.
