Current detailed balance analysis. a Schematic energy band model of hole contact under forward bias. b Plot of theoretical reduced contact resistivity ρc’ (in units of 1/e) against reduced current density Jij’, for different ϕ – ϕpin values, and Gaussian width σG = 0.15 eV. c Plot of ρc’(0) against ϕ – ϕpin. Symbols are computed results; yellow line is guide to the eye for 0.15 < σG < 0.2 eV
