abstract = {Tin sulfide promises very interesting properties such as a
high optical absorption coefficient and a small band gap,
while being less toxic compared to other metal
chalcogenides. However, the limitations in growing
atomically thin structures of tin sulfide hinder the
experimental exploration of these properties. Due to the
flexibility of the colloidal synthesis, it is possible to
synthesize very thin and at the same time large nanosheets.
Electrical transport measurements show that these nanosheets
can function as field-effect transistors with an on/off
ratio of more than 105 at low temperatures and p-type
behavior. The temperature dependency of the charge transport
reveals that defects in the crystal are responsible for the
formation of holes as majority carriers. During illumination
with circularly polarized light, these crystals generate a
helicity dependent photocurrent at zero-volt bias, since
their symmetry is broken by asymmetric interfaces (substrate
and vacuum). Further, the observed circular photogalvanic
effect shows a pronounced in-plane anisotropy, with a higher
photocurrent along the armchair direction, originating from
the higher absorption coefficient in this direction. Our new
insights show the potential of tin sulfide for new
functionalities in electronics and optoelectronics, for
instance as polarization sensors.},
