Using bulk SnS grown by chemical vapor deposition (CVD), I fabricated four-terminal devices via microfabrication processes. From electrical measurements using both the two-terminal and van der Pauw methods, I evaluated the Ohmic contact state of the electrodes and the intrinsic resistivity of the crystal. Consequently, I investigated the impact of excellent crystallinity, including the suppression of grain boundary scattering and the enhancement of carrier mobility associated with CVD growth, on the electrical transport properties.
