We propose that a half semiconducting state can exist in trigonal-prismatic transition metal dichalcogenide (TMDC) monolayers of d$^{1}$ configuration. In that state both electrons and holes are spin polarized and share the same spin channel. On the basis of hybrid density functional theory, we predict in particular that VS$_2$ monolayers are half semiconductors with a direct band gap. Moreover, we find that the conduction electron spin orientation of VS$_2$ switches under moderate strain. Our…
