ABSTRACT
Blocking heat in two ways Low thermal conductivity is important for barrier coatings, thermoelectrics, and other applications. Gibson et al . combined complementary methods that manipulate internal interface properties to dramatically decrease the of inorganic material BiO 2 Cl Se (see Perspective by Kim Cahill). The authors took advantage both in-plane structural distortions weak bonding layers push down 0.1 watts per kelvin meter: only four times air. principles should be applicable systems provide a method developing crystals with extremely low conductivity. —BG
