LEDs developed with Van der Waals heterostructures

LEDs developed with Van der Waals heterostructures

February 20, 2015: A team of researchers at University of Manchester and University of Sheffield in the UK have developed a new type of LED by stacking up several 2D materials like metallic graphene, insulating hexagonal boron nitride and various semiconducting monolayers made from transition metal dichalcogenides (TMDCs). The devices emit light from their surface and have a high quantum ...

EU project develops LED modules capable of spreading uniform light over large areas

LASSIE project

February 18, 2015: Green alternatives to conventional lighting such as LED bulbs are increasingly being used in homes and offices due to their high efficiency and extremely long lifetimes. In contrast, their use in the lighting of architectural features and large public spaces has to date been limited. Key problems include a perceived decrease in light intensity and strength along ...
