Resistivity, Lorenz number and mobility of MoP. a Temperature dependent resistivity, ρxx for \({\mathbf{I}}||{\hat{\mathbf{x}}}\). The inset shows the best fit with ρxx = ρ0 + AT2 + BT5 for the region T < 40 K, where the values of ρ0, A and B are 6.0 × 10−9 Ωcm, 2.3 × 10−12 ΩcmK−2 and 3.6 × 10−16 ΩcmK−5, respectively. b Temperature dependent ρxx at 0 and 14 T when \({\mathbf{I}}||{\hat{\mathbf{x}}}\) and \({\mathbf{B}}||{\hat{\mathbf{z}}}\). The inset shows a significant magnetoresistance below 40 K. c Temperature dependent normalized Lorenz number, L/L0, where L0 is the Lorenz number. The error bar comes from the error in the thermal conductivity measurement (See Supplementary Fig. 7). A strong violation of the Wiedemann–Franz law is observed below 40 K. d Temperature dependent charge-carrier mobility, μ, of MoP. The inset of d shows the crystallographic directions in the hexagonal representation in which \({\hat{\mathbf{x}}}\), \({\hat{\mathbf{y}}}\) and \({\hat{\mathbf{z}}}\) are defined as \([2\bar 1\bar 10]\), \([01\bar 10]\) and [0001], respectively
