Here, we study this system at the commensurate filling of $\\nu_{\\rm tot}=2$. Our focus is on the $1+1$ filling setting of $\\nu_{\\rm Mo} =\\nu_{\\rm W}=1$, which enables a Kondo lattice description. We find a Kondo semimetal due to the sizable intra-orbital hopping among the electrons in the $\\rm{MoTe_2}$ layer. The Kondo-driven (emergent) flat band is naturally pinned to the Fermi energy.
