Spin electronics  is a quantum technology which aims at adding the spin quantum degree of freedom to conventional CMOS electronics. Since the discovery of the giant magnetoresistance in 1988 [2,3], considered as the birth of this field, spintronics continues flooding the market with plethora of devices used in everyday life applications such as hard drive read heads or magnetic random-access memories, and so on. From a fundamental research perspective, the field is still blooming bringing post-CMOS perspectives technologically closer to the reality with, for instance, prototypes of all-spin-logic circuits and neuromorphic chips. To sustain this intense research activity, a quest for new platform materials is also taking place not only to enhance existing performances but also to generate novel functionalities. In this vein, carbon nanostructures such as molecules , graphene, and carbon nanotubes  are among the most sought-after materials.
During this presentation, I will first detail the context of our research and the recent challenges for achieving spin-logic circuits. I will focus on the physics of lateral spintronics devices and then I will detail our approach for reaching giant spin signals in functionalized multiwall carbon nanotubes . I will focus on the necessity to consider new hybrid interfaces are highlighted for a better control of the spin injection at the device level . I will for instance describe our most recent work concerning spin transport across graphene/molecule interfaces.
