I will present our recent work on nitride nanowire based light emitters. These nanomaterials have the potential to boost the device performance, to improve the energy efficiency, to reduce the cost and to bring new functionalities. In particular, I will discuss our recent progress towards flexible nitride nanowire devices. We propose a method to combine high flexibility of polymer films with high quantum efficiency provided by nitride nanowires to achieve flexible inorganic light emitting diodes and light sensors. I will also discuss the fabrication and characterization of single nanowire light emitting diodes with graphene transparent contacts the structural characterization of these nanowires using charge collection microscopy, the possibility to control the LED color by a post-growth treatment as well as the coupling of single nanowire emitters with waveguides in order to form a functional photonic platform.
Bio: Tchernycheva Maria, born in 1979, is an engineer from the Ecole Polytechnique ( X98 ) with a doctorate in physics from the University of Paris Sud (2005). Between 2005 and 2006 she worked as a postdoctoral researcher at the Laboratory of Photonics and Nanosctructures on the development of semiconductor nanowires. In 2006 Maria Tchernycheva joined the Institute of Fundamental Electronics as CNRS researcher. His works are focused on the Current Development of optoelectronic devices such as photodetectors, light emitting diodes, devices for energy scavenging and basic semiconductor nanowires.
