Fig. 3: BAs thermal conductivity vs. doping concentration.
From: How dopants limit the ultrahigh thermal conductivity of boron arsenide: a first principles study

Lattice thermal conductivity of BAs vs doping concentration at 300 K for each of the considered impurities. Solid lines: neutral impurities. Dotted lines: charged impurities. Colored arrows indicate the difference between charged and neutral impurity concentrations that produce a 50% reduction in the BAs κ.
