Nanoscale heat flow plays a crucial role in many modern electronic and optoelectronic applications, such as thermal management, photodetection, thermoelectrics and data communication. Two-dimensional layered materials are beginning to confirm their groundbreaking role in many of these applications. Perhaps even more promising are so-called van der Waals heterostructures, consisting of different layered two-dimensional materials stacked Read more about Fast flowing heat in graphene heterostructures[…]
