Abstract
Electroluminescence in mid-IR of hBN-encapsulated graphene under large bias was recently put into evidence through spectroscopy and noise thermometry. We demonstrate in this presentation that hyperbolic phonon polariton electroluminescence is responsible for efficient out-of-plane energy transfer through hBN. We then show that this energy transfer can be engineered using hBN with various turbidity, exhibiting for the first time that far-field energy transfer in turbid media remains valid in the case of energy transfer by confined hyperbolic rays.
