      abstract     = {Time reversal dictates that nonmagnetic, centrosymmetric
                      crystals cannot be spin-polarized as a whole. However, it
                      has been recently shown that the electronic structure in
                      these crystals can in fact show regions of high
                      spin-polarization, as long as it is probed locally in real
                      and in reciprocal space. In this article we present the
                      first observation of this type of compensated polarization
                      in MoS2 bulk crystals. Using spin- and angle-resolved
                      photoemission spectroscopy (ARPES), we directly observed a
                      spin-polarization of more than $65\%$ for distinct valleys
                      in the electronic band structure. By additionally evaluating
                      the probing depth of our method, we find that these valence
                      band states at the point in the Brillouin zone are close to
                      fully polarized for the individual atomic trilayers of MoS2,
                      which is confirmed by our density functional theory
                      calculations. Furthermore, we show that this spin-layer
                      locking leads to the observation of highly spin-polarized
                      bands in ARPES since these states are almost completely
                      confined within two dimensions. Our findings prove that
                      these highly desired properties of MoS2 can be accessed
                      without thinning it down to the monolayer limit.},
