Le photovoltaïque solaire en France : réalité, potentiel et défis (http://solairepv.fr/)
L’origine anthropique du réchauffement climatique ne fait plus de doute, et l’accord de Paris adopté en 2015 par la quasi-totalité des pays du monde a fixé l’objectif d’une augmentation moyenne de la température inférieure à 2°C. La transition énergétique est … Continued
Measuring the active dopant concentration at the nanoscale
In a series of two articles recently published in Phys. Rev. Applied, we show how cathodoluminescence mapping can be used to provide a contactless, quantitative assessment of active doping at the nanoscale. The method is applied to n-doped and p-doped … Continued
