... regime, and the maximum heat flux is along the  crystalline direction. The mechanisms for the large radiative heat flux are explained as due to existence of hyperbolic phonon polaritons (HPPs) inside α -MoO 3 and excitation of hyperbolic surface phonon polaritons (HSPhPs) at the vacuum/ α -MoO 3...
