# Liu et al., ACS Nano 8, 5304 (2014), Fig. 4e/4f: sensor response of a CVD MONOLAYER
# MoS2 FET with Schottky (Ti/Au) contacts, room temperature. NO2 measured in the ON
# state (V_BG = 30 V), NH3 in the OFF state (V_BG = 0 V). Paper definition
# S_Liu = dG/G0*100 (plotted as -dG/G0 for NO2). Digitised from the 600 dpi render
# (marker centroids, axes calibrated on the major ticks; y read-off uncertainty ~2 %).
# S_model = G0/G - 1 = sigma0/sigma - 1 [%] is the manuscript convention (NH3 < 0).
