WebSep 25, 2013 · Recently, it has been found that the basal-plane thermal conductivity of SLG or bilayer graphene (BLG) in contact with an amorphous inorganic or organic layer is a factor of three to five lower than those found in high-quality graphite and suspended graphene at room temperature ( 11, 12 ). WebHexagonal boron nitride (h-BN) is a natural hyperbolic material, for which the dielectric constants are the same in the basal plane (epsilon^t = epsilon^x = epsilon^y) but have opposite signs (epsilon^t*epsilon^z < 0) from that in the normal plane (epsilon^z). Due to this property, finite-thickness slabs of h-BN act as multimode waveguides for ...
