The calculation of Schottky barrier height under different pressure. The natural logarithm of the current as a function of bias at (a) positive and (b) negative sample bias regions. The dashed lines represent fittings by using thermal electron emission theory. (c) Schottky barrier height as function of pressure. Dash lines are linear fittings.
