The study of thermal transport is a major challenge with many fundamental and technological implications. In this context, the rise of low dimension materials opens up a new scale which deeply changes our understanding. The well-established models for conventional bulk crystals fail for one-atom-thick structures and innovative experimental and theoretical approaches are needed. Surprisingly, a huge effort has allowed addressing graphene Dirac electron transport whereas 2D thermal transport is still in its infancy. This intership proposal intends to engineer suspended membranes of 2D materials, as MoS2 to explore the new frontiers of thermal transport.
 The approach combines specific and complementary state-of-the art-expertise in i) the fabrication of complex nano-patterned structures1,3; ii) spatially resolved temperature measurements using Raman spectroscopy; iii) development of original theoretical models in collaboration with theoricians 2
